Triple bonds are found in which hydrocarbon group?

Explanation:
Triple bonds appear in alkynes. An alkyne is a hydrocarbon that contains at least one carbon–carbon triple bond (C≡C). That triple bond consists of one sigma and two pi bonds, requiring the bonded carbons to be sp-hybridized and giving the molecule a nearly linear shape (about 180°). This distinguishes alkynes from alkanes, which have only single bonds, and alkenes, which have one or more double bonds (C=C). Aromatics are ring systems with delocalized pi electrons, not a true C≡C triple bond. Examples include acetylene (ethyne) and propyne. The triple bond also drives characteristic reactions, such as additions across the bond and, for terminal alkynes, relatively acidic hydrogen.
