Structural Representations Of Organic Compounds

Step 1: The reaction starts with the bromobenzene reacting with Mg in ether to form the Grignard reagent (phenylmagnesium bromide).

Step 2: Carbon dioxide is then introduced, which reacts with the Grignard reagent to form benzoic acid upon acidic workup.

Step 3: The benzoic acid undergoes a Hoffmann bromamide reaction, where the amide is converted to an amine, resulting in the formation of aniline.

Thus, the final product formed is aniline (structure in option (1)).
