Question

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

• A. formation of carboxylate ion
• B. more extensive association of carboxylic acid via van der waals force of attraction
• C. Formation of strong intermolecular H-bonding than alcohol
• D. formation of intramolecular H-bonding

Answer 1

The correct option is C Formation of strong intermolecular H-bonding than alcohol

Carboxylic acids have higher boiling points than aldehydes, ketones, and given alcohol of comparable molecular mass. This is because of formation of intermolecular H-bonding. Hence, the correct answer is option (c).
