Alkynes Nomenclature

They have at least one -C≡C- triple bond. They are named with the prefix of the hydrocarbon with the same number of carbons ending in -yne (recommendation A-3.2).

The first term of the series (ethynyl) retains the common name acetylene (C2H2). Groups derived from the alkynes are named as the hydrocarbon of equal number of carbon atoms ending in -ynyl (-ynyl as a substituent) (recommendation A-3.5).
