IUPAC Nomenclature of Alkanes, Alkenes and Alkynes. The position of the carbon atom with the double bond is mentioned in numerals. For example, CH 3 CH=CHCH 2 CH 3 is named as Pentene. In case of multiple double bonds in the carbon chain, Greek numerical prefixes such . Page 1 NAMING ALKYNES ☺ Naming alkynes is just like naming alkanes ☺ To start, replace the ending “ane” with “yne” ☺ Triple bonds get the lowest possible number on the parent carbon chain. Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of \(C_nH_{2n-2}\). They are unsaturated hydrocarbons. Like alkenes have the suffix –ene, alkynes use the ending –yne; this suffix is used when there is only one alkyne .

Alkynes are organic molecules made of the functional group carbon-carbon triple bonds and are written in the empirical formula of \(C_nH_{2n-2}\). They are unsaturated hydrocarbons. Like alkenes have the suffix –ene, alkynes use the ending –yne; this suffix is used when there is only one alkyne . IUPAC Rules for Alkene Nomenclature. The ene suffix (ending) indicates an alkene or cycloalkene. The longest chain chosen for the root name must include both carbon atoms of the double bond. The root chain must be numbered from the end nearest a double bond carbon atom. If the double bond is in the center of the chain, the nearest substituent rule is used to determine the end where numbering starts. The nomenclature of alkynes is analogous to that of alkenes. C=C and C≡C bonds impart characteristic features to NMR and IR spectra of their compounds that aid in their structural identification. Alkenes and cycloalkenes are hydrocarbons with one C=C bond. They are also commonly referred to as olefins.
