Dimerisation in carboxylic acid is due toa)ionic bondb)covalent bondc)...
Intermolecular hydrogen bonding in carboxylic acid results in dimerisation.
Explanation:
Carboxylic acids are organic compounds containing a carboxyl functional group (-COOH) which has both a carbonyl group (C=O) and a hydroxyl group (-OH). Due to the presence of the hydroxyl group, carboxylic acids can form hydrogen bonds with one another.
When two carboxylic acid molecules come close to each other, the hydrogen of one molecule's hydroxyl group can form a hydrogen bond with the oxygen of the carbonyl group of the other molecule. In turn, the hydrogen of the other molecule's hydroxyl group can form a hydrogen bond with the oxygen of the carbonyl group of the first molecule. This results in the formation of a stable dimer, where two carboxylic acid molecules are held together by intermolecular hydrogen bonds.
The dimerisation of carboxylic acids is an important property that affects their physical and chemical properties. For example, the boiling point of carboxylic acids is higher than that of alcohols of similar molecular weight due to the formation of intermolecular hydrogen bonds. Additionally, the solubility of carboxylic acids in water increases with the length of the carbon chain due to the increasing strength of hydrogen bonding between the carboxylic acid molecules.
