Final answer:
Benzoic acid is a carboxylic acid with an aromatic ring, used as a food preservative and produced by oxidizing toluene. Mixed anhydrides of benzoic acid are named alphabetically without the word 'acid,' ending with 'anhydride'. Benzoic acid's chemical formula is C6H5CO₂H.
Step-by-step explanation:
The chemical structure and reactions of benzoic acid are centered around it being a carboxylic acid with an aromatic benzene ring. The compound, often used as a food preservative, is most effectively used in acidic foods and is made through the partial oxidation of toluene. In naming mixed or asymmetric anhydrides of benzoic acid, such as benzoic anhydride, the names of the combining acids are listed in alphabetical order, omitting the word 'acid' and ending with 'anhydride.' The chemical structure of benzoic acid is C6H5CO₂H, and its derivative, benzene-1,4-dicarboxylic acid, is a component for polymers like Kevlar.
