Account for the following:
The boiling points of alcohols decrease with increase in branching of the alkyl chain. It will start from new line.

Text Solution

Verified by Experts

This is because with increase in branching, van der Waals forces of attraction decreases with decrease in surface area, hence boiling point decreases.
