Provide a molecular structure that corresponds to the given name.
(a) benzoic propanoic anhydride

Guida verificata passo dopo passo

Step 1: Understand the name 'benzoic propanoic anhydride'. This name indicates that the compound is an anhydride formed from benzoic acid and propanoic acid.

Step 2: Recall the structure of benzoic acid. Benzoic acid is a carboxylic acid with the formula C₆H₅COOH, where the carboxyl group (COOH) is attached to a benzene ring.

Step 3: Recall the structure of propanoic acid. Propanoic acid is a carboxylic acid with the formula CH₃CH₂COOH, where the carboxyl group is attached to a two-carbon alkyl chain.

Step 4: Combine the two acids to form an anhydride. In an anhydride, two carboxylic acid molecules are joined by an oxygen atom, with the loss of a water molecule. The general formula for an anhydride is RCOOCOR'.

Step 5: Draw the structure of benzoic propanoic anhydride. Connect the carbonyl carbon of benzoic acid to the oxygen, and then connect the oxygen to the carbonyl carbon of propanoic acid. The resulting structure will have a benzene ring attached to one carbonyl group and a propyl group attached to the other.
