Question

Type of isomerism exhibited by but-1- yne and but - 2-yne

Answer 1

the isomerism between but 1- the and but2-yne is positional isomerism

Answer 2

Position isomerism is exhibited by but-1- yne and but - 2-yne

Explanation:

The compounds having similar molecular formula but different arrangement of atoms or groups in space are called isomers and the phenomenon is called as isomerism.

Position isomers have similar molecular formula but different positions of functional group, i.e position of triple bond.

but -1-yne is $CH_3-CH_2-C\equiv CH$ and but -2-yne is $CH_3-C_\equiv C-CH_3$
