उत्तर
\[\ce{\underline{-COOH}}\] is the functional group of carboxylic acid.
Explanation:
The \[\ce{-COOH}\] group, often known as the carboxyl group, is a different functional group found in carboxylic acids. Carboxylic acids are acidic because they include a carbonyl \[\ce{(C = O)}\] and a hydroxyl group \[\ce{(O - H)}\] linked to the same carbon atom.
