Carboxylic Acids

Hi I want to know that why does carboxylic acid have a higher boiling point than alcohol and why carboxylic acids are soluble in water?? Tell me the use of carboxylic acid.

Re: Carboxylic Acids

Well when it has water the carboxylic acids do not combine with a similar molecule to form a dimmer but the hydrogen bonds are generated between water molecules and individual molecules of acid.

The carboxylic acids up to 4 carbon atoms shall mix with water in any proportion.

It has higher boiling point than alcohol because hydrogen bonding may happen between 2 molecules of acid to produce a dimmer in a pure carboxylic acid.



It suddenly doubles the size of the molecule and so increases the van der Waals dispersion forces between one of these dimers and its neighbours – causing in a high boiling point.

Use of carboxylic acid

Sodium salts of organic acids find application in preservatives.

Soaps are sodium or potassium salts of higher fatty acids such as stearic acid.

Food industry uses many organic acids for the production of soft drinks, food products etc.

For example, acetic acid is used in making vinegar.
