Question

The compounds (a) and (b) are realted as:

• A. Chain isomers
• B. Position isomers
• C. Functional isomers
• D. All of the above

Answer 1

The correct option is B Position isomers

Positional isomers : Structural isomers with a difference in the position of multiple bond/functional group/alkyl substituent on the same carbon skeleton (parent chain).

In (a) the position of $-OH$ groups is 1,4
whereas the position of $-OH$ groups in (b) is 1,3
SO, (a) and (b) are position isomers.
