-yne

Hydrocarbons containing a triple bond.

Latin feminine form ‑ina.

These are systematic names of open-chain (aliphatic) hydrocarbons that contain carbon-carbon triple bonds; they are named by replacing the ‑ane ending of the equivalent saturated hydrocarbon (see ‑ane1) with ‑yne. Examples include ethyne (common name acetylene), butyne, and propyne (common name allylene). The general term for a member of the series, with formula CnHn-2, is alkyne. A polyyne is an organic compound containing two or more carbon-carbon triple bonds. See also ‑ene1.
