A

Propan-1-ol, butan-2-ol, butan-1-ol, pentan-1-ol

B

Propan-1-ol, butan-1-ol, butan-2-ol, pentan-1-ol

C

Pentan-1-ol, butan-2-ol, butan-1-ol, propan-1-ol

D

Pentan-1-ol, butan-1-ol, butan-2-ol,propan-1-ol

Text Solution

Verified by Experts

The correct Answer is:
A
With the increases in molecular mass, the boiling point also increases. Amongst isomeric alcohols, the boiling point decreases with branching due to increase in surface area. Therefore, the correct order is
Propan-1-ol lt butan-2-ol lt buan-1-ol lt pentan-1-ol
