Alcohols, Phenols And Ethers

Question

Arrange the following compounds in increasing order of boiling point and account for the order:
(a) 1-pentanol, (b) 2-methyl-2-butanol, (c) 3-methyl-butanol-2.

Solution

In alcohols, the boiling points decrease with increase of branching in carbon chain, because of decrease in van der Waals forces with decrease in surface area. Thus the decreasing order of boiling point is A > C > B
