WebCarboxyl R-COOH Carboxylic acid is a combination of a carbonyl group and a hydroxyl group attached to the same carbon, resulting in new characteristics. The carboxyl group can ionize, which means it can act as an acid and release the hydrogen atom from the hydroxyl group as a free proton (H + ). Webtakes place under acid (or) base catalysis, or upon heating. The formation is generally driven to the completion by separation of the product or removal of water, or both.
