Question

Which type of isomerism is shown by but-1-yne and but-1,2-diene?

• A. Functional isomerism
• B. Chain isomerism
• C. Ring chain isomerism
• D. Position isomerism

Answer 1

The correct option is A Functional isomerism

Functional isomerism is shown by but-1-yne and but-1,2-diene.
Alkynes having four or more carbon atoms are functional isomers of dienes i.e., compounds containing two double bonds.
