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

Solution
The boiling points of alcohols increase with increase in the number of the carbon atoms. Also, the boiling points decrease with increase of branching in carbon chain. Therefore, order of their increasing boiling point.
Methanol <ethanol<  propan-1-ol< butan-2-ol< butan-1-ol< pentan-1-ol.
