alkynen.

Brit.

/ˈalkʌɪn/, U.S.

/ˈælkaɪn/

Forms: 1800s– alkine, 1900s– alkyne.

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: alkyl n., -yne suffix.

Etymology: < alk- (in alkyl n.) + -yne suffix, after German Alkin (1897 in the passage translated in quot. 1899). Compare alkane n., alkene n.With the form alkine compare -ine suffix⁵.

Chemistry.

Any of the series of unsaturated hydrocarbons containing a single triple bond and having the general formula C_nH_2n−2; (more widely) any open-chain or cyclic hydrocarbon with one or more triple bonds between carbon atoms.The simplest members of the alkyne series are C₂H₂(ethyne or acetylene) and C₃H₄ (propyne or allylene).
