What term describes an unsaturated hydrocarbon with a triple bond?

Explanation:
An unsaturated hydrocarbon with a triple bond is called an alkyne. The triple bond indicates unsaturation, meaning fewer hydrogens than a corresponding saturated alkane. Alkynes follow the general pattern CnH2n−2 for acyclic examples, and their chemistry includes additions across the triple bond and, for terminal alkynes, a notable acidity due to the sp-hybridized carbon. This distinguishes them from aromatic compounds (ring systems with delocalized pi electrons), alcohols (have an -OH group), and esters (contain a carbonyl linked to an alkoxy group).
