Detailed explanation-1: -Carboxyl groups are a combination of two functional groups attached to a single carbon atom, namely, hydroxyl (single-bonded OH) and carbonyl (double bonded O) groups. The carboxyl (COOH) group is so-named because of the carbonyl group (C=O) and a hydroxyl group. They include carboxylic acids and amino acids.
Detailed explanation-2: -Carboxyl Group Example Likely the best-known example of a molecule with a carboxyl group is a carboxylic acid. The general formula of a carboxylic acid is R-C(O)OH, where R is any number of chemical species. Carboxylic acids are found in acetic acid and the amino acids that are used to build proteins.
Detailed explanation-3: -The –COOH group indicates the carboxylic acid, mainly found in the benzoic acid.
