Aromatic acids are organic compounds that contain a carboxylic acid group (-COOH) attached to an aromatic ring. The presence of the aromatic ring, which consists of alternating double bonds, gives these acids unique chemical properties. Common examples include benzoic acid and salicylic acid, both of which are used in various applications, including food preservation and medicinal products. These acids are known for their ability to donate protons (H+) in solution, making them weak acids. Aromatic acids can participate in various chemical reactions, such as esterification and electrophilic substitution, due to the stability of their aromatic structure. Their distinct characteristics make them important in both industrial and biological contexts.
