Carboxylic acid have higher boiling points than aldehydes, ketones and even alcohol of comparable molecular mass. It is due to their

Options

A. Formation of intramolecular H-bonding
B. Formation of carboxylate ion
C. Formation of intermolecular H-bonding
D. More extensive association of carboxylic acid via van der Waals force of attraction

Answer

C

Explanation

Due to formation of intermolecular H-bonding in carboxylic acid, association occurs. Hence boiling point increases and become more than the boiling point of aldehydes, ketones and alcohols of comparable molecular masses.
