To solve this problem, we need to identify the product A and the type of reaction.$\\$Given:$\\$• Starting compound is a bromobenzene derivative with a methoxy group (OCH$_3)$ attached.$\\$• Reagent is NaNH$_2. \\$NaNH$_2$ is a strong base and a nucleophile, commonly used in elimination-addition reactions.$\\$Steps:$\\$1. The reaction involves an elimination-addition mechanism known as the benzyne mechanism.$\\$2. NaNH$_2$ abstracts a proton from the benzene ring, forming a benzyne intermediate.$\\$3. The benzyne intermediate is highly reactive and undergoes nucleophilic attack by NH$_2^-$ to form an aniline derivative.$\\$Product A:$\\$• The methoxy group remains unchanged, and the bromine is replaced by an amino group (NH$_2). \\$Reaction Type:$\\$• This is an elimination-addition reaction.$\\$Therefore, the correct option is Option 1, which shows the product with an NH$_2$ group and describes the reaction as an elimination-addition reaction.
