Carboxylic acids basically are organic acids which are distinguished by the existence of a carboxyl group having the formula –C (=O) OH.

Carboxylic are generally said to be polar, and create hydrogen bonds with each other. At elevated temperatures, in vapour stage, they normally subsist as dimeric pairs. Minor carboxylic acids are miscible with water, where as long chain carboxylic acids are insoluble or less soluble in water because of rising hydrophobic temperament of the alkyl chain. Long chain carboxylic acids are usually more soluble in less polar mixtures like ether as well as alcohol.

The acidity of a carboxylic acid usually can be explicated via resonance effects. The outcome of the dissociation of a carboxylic acid is a quality invention in which the negative charge is distributed among the two oxygen atoms. Carboxylic acids can be easily recognized by infrared spectrometry.
