Question

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

पर्याय

• more extensive association of carboxylic acid viavan der Waals force of attraction

• formation of carboxylate ion

• formation of intramolecular H-bonding

• formation of intermolecular H-bonding

Answer 1

formation of intermolecular H-bonding

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.
