Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass. This is due to more extensive association through intermolecular H-bonding.

1. Aldehydes
2. Ketones
3. Carboxylic acids
4. Alcohols

Correct answer: Carboxylic acids

Solution

Carboxylic acids exhibit extensive intermolecular hydrogen bonding due to the presence of both a hydroxyl (-OH) group and a carbonyl (C=O) group, leading to dimer formation and higher boiling points compared to aldehydes, ketones, and alcohols.
