Question

The compounds but-2-ene and but-1-ene are

• A. Tautomers
• B. Position isomers
• C. Functional Isomers
• D. Both B and C

Answer 1

The correct option is B Position isomers

Positional isomers are constitutional isomers that have the same carbon skeleton and the same functional groups but differ from each other in the location of the functional groups on or in the carbonchain.

The two isomers differ in the position of the double bond. So they are positional isomers.
