Many carboxylic acids exist as associated dimers in the vapour state or in aprotic solvents. What is — Aldehydes Ketones and Carboxylic Acids Chemistry Question

💡 Solution & Explanation

Carboxylic acids form strong intermolecular hydrogen bonds. These hydrogen bonds are so extensive and stable that they are not completely broken even when the substance is heated to its vapour state or dissolved in aprotic solvents, leading them to exist largely as dimers.
