Which one of the following is not an isomer of 3-methylbut-1-yne?

A

Pent-1-yne

B

Buta-1, 3-diene

C

Pent-2-yne

D

Penta-1, 3-diene

Text Solution

Verified by Experts

The correct Answer is:

Isomers have same molecular formula but different structures. Buta-1, 3-diene, i.e., option (b) has only four carbon atoms but all others have five carbon atoms. Therefore, (b) is not the isomer of the rest of the compounds.
