Which of the following boiling point order is correct?

A

pentan-1-ol `gt` butan-1-ol `gt` butan-2-ol `gt` propan-1-ol

B

butan-1-ol `gt` pentan-1-ol `gt` butan-2-ol `gt` propan-1-ol

C

butan-2-ol `gt` butan-1-ol `gt` pentan-1-ol `gt` propan-1-ol

D

propan-1-ol `gt` butan-1-ol `gt` butan-2-ol `gt` pentan-1-ol

Text Solution

Verified by Experts

The correct Answer is:
A
As molecular weight increases, boiling point increases and in the isomeric alcohols the boiling point decrease as `1^(@)gt2^(@)gt3^(@)`.
Thus correct decreasing order of boiling point is
pentan-1-ol `gt` butan-1-ol `gt` butan-2-ol `gt` propan-1-ol.
