Carboxylic acid

A carboxylic acid is an organic acid that contains a carboxyl business C=OOH attached to an R-group. a general formula of a carboxylic acid is R−COOH or R−CO₂H, with R referring to the alkyl, alkenyl, aryl, or other group. Carboxylic acids occur widely. Important examples put the amino acids as well as fatty acids. Deprotonation of a carboxylic acid permits a carboxylate anion.

Carboxyl radical

The carboxyl radical, •COOH, only exists briefly. The acid dissociation constant of ^{•COOH has been measured using electron paramagnetic resonance spectroscopy. The carboxyl group tends to dimerise to clear oxalic acid.}
