Question

The type of isomerism existing between the pair of compounds 2-chloro propane and 1-chloro propane is

Answer 1

Explanation:

Correct option is

A

(i) Chain isomerism (ii) Functional isomerism (iii) Position isomerism

(i) Pentan-1-ol and 3-Methylbutan-1-ol: Both have the same number of carbons but the length of the parent carbon chain is different. Thus the pair shows chain isomerism.

(ii) Ethanol and Dimethyl ether: Both have the same number of atoms but form two classes of functional groups of organic compounds i.e. alcohol and ether, respectively. Thus they show functional isomerism.

(iii) Butan-1-ol and Butan-2-ol: The position of the functional group in the parent chain is different. Thus shows position isomerism.
