Arrange the following compounds in increasing order of boiling point :
Propan-1-ol, butan-1-ol, butan-2-ol, pentan-1-ol

A

Propan-1-ol `lt` butan-2-ol `lt` butan-1-ol `lt` pentan-1-ol

B

Propan-1-ol `lt` butan-1-ol `lt` butan-2-ol `lt` pentan-1-ol

C

Pentan-1-ol `lt` butan-2-ol `lt` butan-1-ol `lt` propan-1-ol

D

Pentan-1-ol `lt` butan-1-ol `lt` butan-2-ol `lt` propan-1-ol

Text Solution

Verified by Experts

The correct Answer is:
A
With the increase in molecular mass, the boiling points also increase. Amongest isomeric alcohols, the boiling point decreases with branching due to decrease in surface area.
