Question

Which of the following compounds are related as chain isomers ?

• A.
• B.
• C.
• D.

Answer 1

Answer: (A), (B), (D)

The correct options are
A
B
D

Structural isomers which have different carbon skeletons
(parent chain or side chain)
Chain isomerism is also known as skeletal isomerism.
These compounds have same molecular formula , general formula and emperical formula.
Molecular formula of (a),(b) and (d) is $C_6{H}_{14}$.
Molecular formula of (c) is $C_5{H}_{12}$
So (a) , (b) and (d) are chain isomers of each other.
