Which suffix indicates a carbon–carbon triple bond?

Explanation:
In naming hydrocarbons, the ending shows the type of bond between carbon atoms. A triple bond is signaled by the suffix -yne, which defines alkynes. The simplest example is ethyne, where the two carbons are connected by a triple bond. This distinguishes it from -ane (single bonds, alkanes) and -ene (double bonds, alkenes), and from -diene (two double bonds). So the suffix that indicates a carbon–carbon triple bond is -yne.
