According to IUPAC nomenclature methods, such complex substituents should be in the brackets of their corresponding compounds. Lowest locant rule: Carbon bearing the multiple bond gets the lowest possible locant. Examples of this compound are ethene, propane, etc. In the given example “5-methylhex-3-en-2-ol” there are 4 pieces- ‘methyl’, ‘hex’, ‘en’ and ‘ol’. If both substituent and multiple bond are present, the priority order is: If multiple bonds are present at equivalent position, follow alphabetical order i.e double bond(-ene) gets higher priority than triple bond(-yne). An example of this group is ethyne. Bromo Propane OR Propyl bromide. Here, the substituents represent functional groups attached to the primary carbon chain. The suffix ‘ane’ is used to describe any alkane compound - for instance, methane, ethane, butane, etc. Trivial nomenclature system involves a non-systematic approach while naming any compound. Steps for Writing IUPAC Name. Some examples of IUPAC names for compounds containing one functional group: The priority order of functional groups is: -COOH > -SO3H > – COO- > -COX > -CONH2 > -CN > -CHO > -CO- > -OH > -NH2. A common example of this group is anediol, anetriol, pentanol, butanediol, etc. The use of prefix is very useful, as it shows the existence of side chains and substituent groups of an organic molecule. The Chemical Abstract Service has adopted a nomenclature system in which the suffix -amine is attached to the root alkyl name. Naming Primary Amines. Structural … On the other hand, other groups or substituents adds prefixes to root names. Prefix is added in front of the root names of compounds under this nomenclature. When other functional groups have naming priority, – … If two or more equally long chains are present, the chain with maximum number of substituent is selected as the parent chain. Here, ‘ene’ indicates the shift to double bonds. IUPAC Nomenclature of Alkyl halide or Haloalkanes * In substitutive system of IUPAC nomenclature, the alkyl halides are named as "Haloalkanes". Structural formula No. Eg. Ethers are known with their common names. Examples of this compound are ethene, propane, etc. However, it may vary from using common and colloquial terminologies to strict rules. For example, ‘cyclo’ prefix is used for cyclic compounds. Hence the IUPAC name of thhe compound is 3-bromobutanoicacidExample 2 1 CH2 CH CH3 3 5 HO CH 4CH 2 CH3 4-methylpent-2-en-1-olIn the above given example1 Prefix= Methyl2 Root word = Pent3 Primary suffix= ene4 Secondary suffix = ol5 Number of Carbons = 5Hence the name of the given compound is 4-methylpent-2-en-1-ol Sometimes, in case of compounds having polyfunctional groups, functional groups may be considered as prefixes. It is added to the name, after the primary suffix. Conjunctive: It is used for combining named subunits. Step III – Naming : Substituents are written in alphabetical order as mentioned earlier. This is a method of naming the organic compounds as recommended by the international Union of Pure and Applied Chemistry (IUPAC). This is the brief summary of naming a primary amine: Step 1. Figure out the chirality centre and other stereogenic units, namely double bonds. CH 3 -CH 2 -CH 2 -CH 2 -CH 2 -CH 3 Note : We skip 'e' from the end of the primary suffix when secondary suffix (explained later) starts with a vowel. IUPAC nomenclature decides the fundamental root name by using the longest continuous chain of carbon. Hence (2,2,4) is lowest set of numbering and is correct numbering. X = Cl, Br, I, F. CH 3-Cl. Even though this chapter is a little technical, a guided study can make it easy. Naming amines by the systematic nomenclature follows the same rules we discussed earlier for the IUPAC nomenclature rules for alkanes. Saturated ane 2. Similarly: The IUPAC name of the propanaldehyde molecule can be written as Propanal, CH 3 –CH 2 … Pro Subscription, JEE The IUPAC rules applied for monofunctional compounds are also applied for polyfunctional compounds. It is considered as a substituent of alkane chains. Hence, with the help of this nomenclature, such problems can be circumvented. Step-II : Numbering the parent chain : Principal functional group gets lowest locant(number). In such cases, the last letter. The presence of the function may be indicated by a characteristic suffix and a location number. Note : Here the first locant is same (i.e 2) so compare second locant which is 2 and 4 in (2,2,4) and (2,4,4). Nitrobenzene : Laboratory preparation, Properties and Uses. If substituents are present at equivalent position, follow alphabetical order. These classes are conducted by experts from across the country and are interactive, which lets students get ample opportunities to clear their doubts. Moreover, functional groups of the highest priority modify the suffix. This main carbon chain is the longest possible continuous one. Note: If both double and triple bonds are present, the terminal ‘e’ of first one(in name) is dropped(removed). In this system, a root word is chosen based on the number of carbon atoms present in the parent chain and then the primary suffix … Now customize the name of a clipboard to store your clips. In chemical nomenclature, the IUPAC nomenclature of organic chemistry is a systematic method of naming organic chemical compounds as recommended [1] by the International Union of Pure and Applied Chemistry (IUPAC). A secondary prefix portrays the existence of substituent groups and side chains. A prominent example of its use is the CH3 group, which is known as a methyl group. In the IUPAC system of nomenclature, functional groups are normally designated in one of two ways. Note: If primary suffix begins with consonant like di, tri, tetra, etc. Prefix : It indicates the substituent ( i.e any group bonded with parent carbon chain except main functional group). Find out the senior-most among these structural components joined to the primary characteristic group. However, when one hydrogen is removed from the end of a chain, it changes the suffix ‘-ane’ to ‘-yl’. It requires following a step by step method to form a nomenclature of organic compounds. Eg. For instance, compounds with alcohol and alkane group attached to them will be termed as an alkanol, here ‘ol’ is the secondary suffix for the alcohol group. Primary suffix : It indicates the nature of carbon to carbon bond in the parent carbon chain. It is the prevailing body responsible for regulating atomic weights, symbols, nomenclature, etc. Thus, if there are any second bonds, then the suffix expands to include a prefix. IUPAC names the longest continuos chain including the C of – CH = O and replaces – e of the alkane name by the suffix – al i.e. Similar to the system mentioned above, when a double bond expands to a triple bond, the suffix ‘-yne’ is used. Step-I : Selection of parent chain : The longest continuous carbon chain with principal functional group is selected as the parent chain. Such prefixes provide an insight into the acyclic and cyclic nature of compounds. The infixes are sometimes called as primary prefixes. The primary suffix is used immediately following the root word. It is found in chocolate, as well as in a number of other foods, including the leaves of the tea plant, and the kola nut.It is classified as a xanthine alkaloid, others of which include theophylline and caffeine. Determine The Functional Group That Will Be Cited As The Suffix. Ghosh, S.K., Advanced General Organic Chemistry, Second Edition, New Central Book Agency Pvt. The general formula of an alkyne is C. Alcohols are named after replacing the ‘–ane’ suffix with ‘-anol’. It is saturated so the primary suffix should be “ane” but as there is a functional group (alcohol) “–OH” in the molecule, remove the “e” from the name of the molecule and add the secondary suffix “ol”. During nomenclature of polyfunctional compounds, fuctional group of higher priority is taken as principal functional group and other functional groups are considered as substituents. Headquarters of this organisation are located in the USA. Therefore, compounds that have derived their name via this system has a much simple name compared to others. The number of organic and inorganic compounds are increasing every day. Categorise the substituents, and then organise them in alphabetical order according to their corresponding prefixes. Need help paying your bill? For example. Primary Suffix Primary suffix is used to represent saturation or unsaturation in the carbon chain. The use of prefix is very useful, as it shows the existence of side chains and substituent groups of an organic molecule. If there are more than once hydroxyl group, then, this suffix is expanded to include a proper prefix. Unsaturated with One double bond Two double bond Three double bond ene diene triene 3. Prefix: Prefix is added in front of the root names of compounds under this nomenclature. [B] Compounds containing multiple bonds ( double/ triple bonds) too. To simplify the nomenclature process, differentiate the organic compounds in four categories as. Suffix: Suffix in IUPAC nomenclature refers to the functional group it belongs to and follows the root name. In the nomenclature of Alk… Such prefixes provide an insight into the acyclic and cyclic nature of compounds. Nomenclature is the process of naming living and non-living substances. Double bonds of unsaturated hydrocarbons are regarded as an alkene. To name the large number of organic compounds, a scientific and logical approach was developed. CH 3-CH 2-CH 2-Br. Primary suffix =ene Substitute : ethyl Secondary prefix + primary prefix +word root + Primary suffix+ seondary suffix IUPAC name: 4-Ethyldeca-1, 5, 8-triene 3. IUPAC stands for International Union of Pure and Applied Chemistry. alkanal. Suffix: Suffix in IUPAC nomenclature refers to the functional group it belongs to and follows the root name. Here, substances are named according to their highest priority conditional groups. Format used for this purpose is – “locant + prefix + root + locant + suffix”. You just clipped your first slide! Being aware of the IUPAC nomenclature is essential for students preparing for their chemistry exams. Combine the suffix and parent hydride name to determine the principal characteristic group. Primary suffix: ane The IUPAC names of alkanes are obtained by adding suffix ane to he word root indicating the number of carbon atoms. Remember only two things (mentioned below) during nomenclature, you will easily write correct IUPAC name of all organic compounds. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. Additionally, ‘di-’ prefix is used in case both alkyl groups are the same. Finar, I. L., Organic Chemistry, Vol. There are two types of suffixes: Primary Suffix; Secondary Suffix; Primary Suffix: It is used to indicate whether the parent chain is saturated or unsaturated. e.g. Some examples of this group are diethyl ether, ethyl methyl ether, etc. is written before the name of secondary suffix with respective locant numbers. Substitutive: It is probably the most common way of modifying a compound’s root name. Hence, students struggling with this chapter can attend the live classes via Vedantu app. This prefix indicates the number of bonds. Some functional groups are also indicated as prefixes. For 1º-amines such as butanamine (first example) this is analogous to IUPAC alcohol nomenclature (-ol suffix). An example of this group is ethyne. However, the carbon attached to this group is numbered 1. However, the terminal ‘e’ is retained if the complete secondary suffix begins with a consonant. It Will Determine The Prefix Of A Compound’s Name. The terminal 'e' of the primary suffix is usually removed before attaching the secondary suffix. Before starting the IUPAC rules, lets see an example of organic compound and it’s IUPAC name. Step III – Naming : Alphabetically i.e. Nature of carbon chain (parent chain) Primary suffix 1. Why Is Nomenclature Vital For Chemistry? Eg. The general formula of an alkyne is CnH2n-2. For instance, ketone, alkyl halide, alcohol, etc. The body improves and keeps these data to aid chemists and researchers across the globe. For example: Naming of all organic compounds can be done in three steps as. Primary suffix IUPAC name and Formula; 1. if more than one substituents are present then they are written in the alphabetical order. I and Vol. Functional Groups: Here, substances are named according to their highest priority conditional groups. {Note: -NH2 can be taken as substituent as well as functional group}. Formula of alkene is CnH2n. The C of CHO is number 1. The primary suffix denotes the number of covalent bonds between the carbon atoms. Ideally, every possible organic compound should have a name from which an … Eg. Prefix → 3 – bromo 2 – chloro 3, 4 – diethyl 4 – methyl 2 – nitro. It is used to indicate the main functional group in the organic compound and is added immediately after the 1o suffix. Step III – Naming : Always follow this format: NOTE : While adding the secondary suffix to the primary suffix, the terminal ‘e’ of the primary suffix (i.e., ane, ene or yne) is dropped if the secondary suffix begins with a vowel. There are various ways to modify the root name of a compound according to its functional group. Alkanes can be an open chain, or it can be in a ring(cycloalkane). https://iupac.org/what-we-do/nomenclature/. Suffix in IUPAC nomenclature refers to the functional group it belongs to and follows the root name. IUPAC’s full form is International Union of Pure and Applied Chemistry. Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. Locant is a number that locate the position of substituent. 2. Some other examples of polyfunctional compounds : Nomenclature of organic compounds is very easy. While writing the name, primary suffix is added to the word root. Unsaturated with One triple bond Two triple bond yne diyne Sl. They can also access various study materials. Pro Lite, NEET It is probably the most common way of modifying a compound’s root name. Alkyl Halides: It is considered as a substituent of alkane chains. In order to find that, two alkyl groups are attached to an oxygen atom, and then put them in alphabetical order with space between names. Alkyl halides are regarded as an equal of alkyl substituent in the parent numbering chains. Alkene: Double bonds of unsaturated hydrocarbons are regarded as an alkene. 2. Due to their widespread use, some compounds are registered under IUPAC nomenclature according to their trivial names. Alkynes: Similar to the system mentioned above, when a double bond expands to a triple bond, the suffix ‘-yne’ is used. Similar to the suffix, a prefix is also divided into two categories - primary and secondary. Always write the name in general format : Failed to subscribe, please contact admin. Note: R-X → alkyl halide or haloalkane. If there are more than once hydroxyl group, then, this suffix is expanded to include a proper prefix. This process indicates when a carbon atom is getting replaced by another atom. Eg. Here, ‘ene’ indicates the shift to double bonds. In chemistry, a number of prefixes, suffixes and infixes are used to describe the type and position of the functional groups in the compound. Filed Under: Chemistry, Class 11, Organic Chemistry - Some Basic Principles and Techniques Tagged With: 3 basic primary suffix, IUPAC system, Nomenclature, prefix, primary prefix, primary suffix, rules for IUPAC Nomenclature of organic compounds, secondary prefix, secondary suffix, suffix, Trivial or common name, word root. CH 3 CH 2 CH 2 CH 3 5. Alkyl halides are regarded as an equal of alkyl substituent in the parent numbering chains. Add multiplicative prefixes without altering the current order. Secondary suffix are words added after the primary suffix to indicate the presence of a functional group ( like aldehydic group, ketonic group, alcoholic group, etc) in the carbon chain. If the given compound is an alicyclic compound, then a prefix cyclo is used just before the root word. Ethers: Ethers are known with their common names. Secondary suffix : It indicates the parent(main) functional group present in the compound. It is added after primary suffix. A secondary prefix portrays the existence of substituent groups and side chains. Under this IUPAC nomenclature of organic chemistry, there is a set of rules that every chemist must follow to name compounds belonging to particular groups. Various principals agreed internationally are used for this purpose. of various chemicals. II, Prentice Hall, London, 1995. Step III – Naming : Alphabetically i.e. This organisation is also responsible for creating the IUPAC nomenclature for inorganic and organic compounds. It is published in the Nomenclature of Organic Chemistry (informally called the Blue Book). Locate The Longest Carbon Chain With The Required Functional Group And Add Up The Number Of Carbon Atoms. Need help with your login or our website? Some additional rules are needed, which are given below: At first, principal functional group is identified according to priority order. If a compound contains two or more functional groups, the words –di, -tri, -tetra, etc. CH 3 CH 2 CH 3 4. After that, this root name is modified with assistance from various functional groups that substitutes carbon and hydrogen atoms in the main structure. Note: If there are two or more functional groups in a compound, the functional group with higher priority is to be selected as main functional group, which must be indicated by a secondary suffix. Suffixes. The primary and secondary suffix play an important role in Nomenclature. For instance, ketone, alkyl halide, alcohol, etc. CH 3 CH 2 CH 2 CH 2 CH 3: Meth - Eth - Prop - But - Pent - ane - ane - ane-ane - ane: Methane CH 4 Ethane C 2 H 6 Propane C 3 H 8 Butane C 4 H 10 Pentane C 5 H 12 Primary suffix an(e) in 4-chlorocyclohexan-1-ol suggests that the carbon chain is saturated i.e all carbon atoms are linked to one another by a single bond. Choose Your Exam Partner Wisely, Opt For Vedantu, Organic Compounds - Structural Representation, Vedantu Additionally, a student aspiring a career in chemistry must know this section very well. To comply with IUPAC norms, a suffix is used as part of the name of a particular compound. Additionally, complex substituents of any organic compound having a branched structure should be regarded as substituted alkyl groups. Each part of the IUPAC name gives you some useful information about the compound. √ There are three components of an IUPAC name. For example, alkanes, where ‘ane’ is the suffix used just after the root word. Bahl, B.S., A., Advanced Organic Chemistry, S. Chand and company Ltd, New Delhi, 1992. The suffix used on various cases are- ⇒Secondary suffix: The secondary suffix tells us about the characteristic functional group present in the organ ic compound. Repeaters, Vedantu [A] Compounds containing carbon to carbon single bonds and substituents only. IUPAC has a prolonged history of providing nomenclature to organic and inorganic compounds. Additionally, the chemical ending represents the molecule’s type. Typically, the terms used every day to describe an organic nor inorganic substance, are registered as its official name. Step-I : Selection of parent chain : The longest continuous carbon chain is selected as the parent chain. Step-I : Selection of parent chain : The longest continuous carbon chain including functional group is selected as the parent chain. This naming system has been developed to create a set of standardised names that are accepted across the globe. Now see the four parts ( prefix, word root, bond and functional group) separately. General steps for IUPAC nomenclature of organic compounds: IUPAC Nomenclature of organic compounds containing carbon to carbon single bonds and substituents only : [A], IUPAC Nomenclature of organic compounds containing multiple bonds(double/triple bond) too. Step-II : Numbering the parent chain : Now the final priority order for numbering is : Functional group > Multiple bond > substituent. To understand the name you need to take the name to pieces. Some primary suffixes are given below. In the IUPAC system, the name of the organic compound consists of Secondary prefix + Primary prefix + Word root + Primary Suffix + Secondary Suffix Nomenclature of Alkanes Alkanes are hydrocarbons which have no double bond or triple bond. . In order to find that, two alkyl groups are attached to an oxygen atom, and then put them in alphabetical order with space between names. Replacement: This process indicates when a carbon atom is getting replaced by another atom. No. ‘en’ tells that there is at least one carbon to carbon double bond. Word root → Hept. It is further segregated into two types - primary and secondary. No. then extra “a” should be added to word root. For example, alkanes, … Lowest locant rule: Carbon bearing the substituent gets the lowest possible locant. of C atoms Root word Primary suffix Primary prefix IUPAC name 3 Prop ane Cyclo Cyclo propane 4 But ane Cyclo Cyclo butane H 2 C CH 2 C H 2 H 2 C H 2 C CH 2 CH 2. Primary suffix → ane. Alcohols: Alcohols are named after replacing the ‘–ane’ suffix with ‘-anol’. For example. 1. root word ; primary suffix; secondary suffix; The root word example meth , eth , but depends on the number of carbon atoms in the compound. Root word; Suffix; Prefix (i) ROOT WORDS. Organic compound Word root Primary suffix IUPAC name CH 2 CH 2 CH 3 Prop ane Propane CH 2 = CH 2 Eth ene Ethane CH 3 C≡CH Prop yne Propyne CH 2 = CH – CH = CH 2 But dine Butadiene (b) Secondary suffix Secondary suffix gives the idea about nature of the functional group present in the compound. For the following compounds, write structural formulas and IUPAC names for all possible isomers having the number of double or triple bond as indicated: (a) C4H8 (one double bond) (b) C5H8 Internationally agreed principals are used for naming different compounds. A secondary suffix is written after the primary one. [C] Compounds containing one functional group ( monofunctional compounds). Trivial: Due to their widespread use, some compounds are registered under IUPAC nomenclature according to their trivial names. Clipping is a handy way to collect important slides you want to go back to later. The word comes the Latin word ‘nomen’ which means name, and ‘calare’, i.e. Sorry!, This page is not available for now to bookmark. Nomenclature is the process of naming substance, both living and non-living. 4. Root: This term specifies the total number of carbon atoms that exist in a long carbon chain of an organic compound. Creating these systematic names is a complicated process. The primary suffix is used immediately following the root word. Thus, general format for IUPAC name of all compounds is: IUPAC name of all compounds contain word root and primary suffix but prefix and secondary suffix may not be present because all organic compounds must contain carbon chain and bond but substituent and functional group may not be present. The IUPAC name is 3-bromo 2, 4, 4 –trichloro 3-iodo 2-methyl hexane. ‘hex’ tells that there are 6 carbon atoms on parent carbon chain. For instance, ‘meth’ refers to the chain with one carbon atom, and ‘non’ indicates nine carbon atoms in an organic compound. Therefore the IUPAC name will be Butane. Pro Lite, Vedantu It was founded in 1919 as a replacement for the International Congress of Applied Chemistry. Step-I : Selection of parent chain : The longest continuous carbon chain including multiple bond is selected as the parent chain. 3. ‘methyl’ tells that –CH3 is present as substituent. Next, the appropriate primary suffix must be added to the root word to indicate the saturation or unsaturation. Ltd., Kolkatta, 2007. https://en.wikipedia.org/wiki/Preferred_IUPAC_name. This is common for the carbon-carbon double and triple bonds which have the respective suffixes - ene and - yne. They are trailed by the word ether. Primary suffix A primary suffix is added to the Root word to indicate whether the parent chain is saturated or unsaturated. Therefore, if there are no rules and regulation in place, it will be very difficult to find any substance. Prefix (alphabetically) root word (alk) primary suffix (ene, yne) secondary suffix (main functional group) So IUPAC name of any organic compounds essentially consists of two or three parts. Alkanes: Alkane is a type of saturated hydrocarbon, and its formula is CnH2n+2. CH 3 –CH 2 –OH : Eth + an + ol : Ethanol. CH 3 CH 3 3. About Mrs Shilpi Nagpal The basic unit is a series of root words which indicate linear or continuous chains of carbon atoms. The first step in giving IUPAC name to an organic compound is to select the parent chain and assign a root word. On the other hand, other groups or substituents adds prefixes to root names. For compounds with two – CHO groups, the suffix – dial is added to the alkane name. It is further segregated into two types - primary and secondary. Thus, general format for IUPAC name of all compounds is: IUPAC name of all compounds contain word root and primary suffix but prefix and secondary suffix may not be present because all organic compounds must contain carbon chain and bond but substituent and functional group may not be present. Nomenclature is used in every branch of science, and in this section, IUPAC nomenclature for organic compounds will be discussed. 3. call. of various chemicals. [B], IUPAC Nomenclature of organic compounds containing one functional group ( monofunctional compounds): [C], IUPAC Nomenclature of organic compounds containing more than one functional groups ( polyfunctional compounds) : [D], https://app.biorender.com/illustrations/edit/5ed85ef66c525700aadc31bf, Ozone – Preparation, Uses, Test, Ozone layer depletion, Lassaigne’s test to detect foreign elements present in organic compounds. The suffix ‘ane’ is used to describe any alkane compound - for instance, methane, ethane, butane, etc. Sl. Suffix trees and suffix arrays in primary and secondary storage Pang Ko Iowa State University Follow this and additional works at:https://lib.dr.iastate.edu/rtd Part of theBioinformatics Commons, and theComputer Sciences Commons In this IUPAC name list below, the nomenclature of some common compounds has been discussed. It is further segregated into two types - primary and secondary. Eg. These are –. Main & Advanced Repeaters, Vedantu There are only three steps in nomenclature of all organic compounds. The primary prefix indicates the acyclic or cyclic nature of any organic compound. Specify unsaturation, if there is any after naming the parent hydride. Therefore, the IUPAC name of ethyl alcohol is “ethanol”. IUPAC stands for International Union of Pure and Applied Chemistry. ‘ol’ tells that there is –OH group(alcohol) as functional group. Furthermore, IUPAC’s nomenclature of organic compounds has three sections - substituents, the length of the carbon chain, and chemical ending. Primary suffix → ane if more than one substituents and multiple bonds are present then they are written in the alphabetical order. Theobromine, formerly known as xantheose, is a bitter alkaloid of the cacao plant, with the chemical formula C 7 H 8 N 4 O 2. [D] Compounds containing more than one functional groups ( polyfunctional compounds). Chloromethane OR Methyl Chloride. Secondary suffix indicates the type of functional group. It develops and maintains such data to aid chemists and researchers across the globe. These principals enforce a standardise rule and eradicate the problem of various names for a single compound. IUPAC is the international governing body for standardising atomic weights, symbols, nomenclature, etc. primary suffix and secondary suffix Primary suffix indicates saturation or unsaturation [for alkane the primary suffix is –ane, alkene –ene and for alkyne –yne]. Find out how to make a payment.. For questions about ID cards, benefits, claims or other issues: Call the number on the back of your member ID card or 313-225-9000. A prominent example of its use is the CH, Alkane is a type of saturated hydrocarbon, and its formula is C. . In general, amines can be named either by systematic or common names. This avoids the confusion of scientists naming substances in different ways. CH 4 2. Then insert locants. Nomenclature of Organic Compounds – IUPAC. Moreover, functional groups of the highest priority modify the suffix. Word root : It indicates the parent carbon chain, which is the the longest continuous chain of carbon atoms including functional group and multiple bonds( if present). It is another part of name that comes after the word root. However, when one hydrogen is removed from the end of a chain, it changes the suffix ‘-ane’ to ‘-yl’.
