IIT-JEE 2007 · Paper 1, Chemistry question 34

STATEMENT-1: pp-Hydroxybenzoic acid has a lower boiling point than oo-hydroxybenzoic acid.

because

STATEMENT-2: oo-Hydroxybenzoic acid has intramolecular hydrogen bonding.

Choose one option
Answer and worked solution

Official answer: D

Statement 1. In the ortho isomer the OH and COOH form an intramolecular hydrogen bond, which reduces intermolecular association, so o-hydroxybenzoic acid boils lower. The para isomer is associated through intermolecular hydrogen bonds and boils higher. Statement 1 is False.

Statement 2. True.

(D)
