Question

Which of the following option is correct regarding given compounds?

• A. Both are functional isomers
• B. Both are chain isomers
• C. Both are ring isomers
• D. Both are positional isomers

Answer 1

The correct option is D Both are positional isomers

(I) is hex-1-ene and (II) is hex-2-ene.
Both compounds differ only in the position of multiple bond (here double bond) on the same parent chain. The principal chain is also the same for both (I) and (II) of six carbon atoms.

So, by definiton they are positional isomers
