Chemistry - STRUCTURAL ISOMERISM Question with Solution | TestHub

A terminal alkyne C₆H₁₀ has the form HC≡C-C₄H₉. The butyl group has four isomers : n-butyl gives hex-1-yne, sec-butyl gives 3-methylpent-1-yne, isobutyl gives 4-methylpent-1-yne and tert-butyl gives 3,3-dimethylbut-1-yne. Hence 4 distinct terminal alkynes.
