Question

Carboxylic acids exist as dimers. Explain

Answer 1

it exists as dimer because it can form a strong hydrogen bond among its own molecules and to greater extent ....Carboxylic acids exist as dimer with two molecules held together by hydrogen bonding,As we see thecarboxylic acid in vinegar can hydrogen bond to each other, and their bonding is to greater extent.

Answer 2

Carboxylic acids exist as dimers due to hydrogen bonding.

• Due to intermolecular hydrogen bonding between the carboxyl groups of two different acid molecules, carboxylic acids can exist as dimers.
• As a polar functional group capable of hydrogen bonding, the carboxyl group made up of a specific carbon atom double-bonded to an oxygen atom and single-bonded to a hydroxyl group causes this to happen.
• The oxygen atoms of the carboxyl groups in two carboxylic acid molecules that are adjacent to one another may make a hydrogen bond.
• This hydrogen bond is made with a hydrogen atom from the other molecule, resulting in the creation of a dimer.
• It is an important process that can change the characteristics and behaviour of carboxylic acids is dimerization.
