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

Options

  1. Amore extensive association of carboxylic acid via van der Waal's force of attraction.
  2. Bformation of carboxylate ion.
  3. Cformation of intramolecular H−H -bonding.
  4. Dformation of intermolecular H−H -bonding.

Correct answer

D. formation of intermolecular H−H -bonding.

Step-by-step solution

Carboxylic acids have higher boiling points than aldehydes, ketones and even alcohols of comparable molecular mass. It

Carboxylic acid has a higher boiling point than aldehyde, ketone and even alcohols of comparable molecular mass.

This is due to their more extensive association through intermolecular H−H -bonding and it forms a dimer.
