Q. Is COOH an alcohol?

No, COOH is not an alcohol. It is a carboxyl group, which defines carboxylic acids. While it contains an –OH component, that hydroxyl group is chemically bonded to a carbonyl carbon, giving it very different properties from alcohols.

Alcohols have a standalone –OH group attached to a carbon atom without a double-bonded oxygen. This structural difference explains why carboxylic acids are acidic, while alcohols are generally neutral. In practice, this distinction affects boiling points, reactivity, and biological behavior.
