Nomenclature of Alkynes Alkynes follow the rules of hydrocarbon nomenclature already discussed. The suffix -yne is used in the base hydro- carbon name to denote an alkane and the position of the triple bond is indicated by its number in the chain Numbering always begins at the chain end nearer the triple bond so that the triple bond receives as low a number a as possibleOrganic Chemistry Organic Chemistry Xiamen Xiamen University University Nomenclature of Alkynes Alkynes follow the rules of hydrocarbon nomenclature already discussed.
