Alcohols, Phenols And Ethers

Question
CBSEENCH12008082

Arrange the following compounds in order of increasing boiling points:
Penta-1-ol, butan-1-ol, butan-2-ol, ethanol, propan-1-ol, methanol.

Solution

Boiling point of alcohol increase with increase in the
number of carbon atoms (increase in van der Waals forces). Thus, order of increasing boiling point,

Methanol < ethanol < propan-1 -ol < butan-2-ol < butan-1-ol < pentan-1-ol.
