The name of a hydrocarbon dictates whether there are single C-C bonds, double C=C bonds, or triple C bonds. This is done by the name ending in -ane, -ene, and -yne. Let’s use common compound ‘methane’ as an example. Methane has a C-C bond because it ends in -ane. Methane is an alk-ANE. Methane has a C=C because it ends in -ene and is an alk-ENE. lastly, methyne has a triple C bond because it ends in -yne and is an alk-YNE.
