Nucleophilic And Electrophilic Substitution Reactions Both Aromatic And Aliphatic

The reaction shows the halogenation of an amide group ( ) with bromine. Pyridine is a mild base and it directs the substitution at the position ortho to the existing group. The reaction produces an intermediate compound .
In the second step, bromine further reacts with the intermediate to give the final product.
Thus, the correct answer is .

Step 1: The reaction involves the halogenation of the aromatic ring in the presence of bromine ( ). This leads to the substitution of a hydrogen atom by a bromine atom in the ring, producing the brominated product. The correct product is the one where the bromine attaches to the phenyl ring in the presence of the carboxylic acid group, forming . Thus, the major product is .
