Answer 1

The given reaction involves a substituted aromatic compound where a carboxyl group (-COOH) and an amino group (-NH2) are present. This reaction uses bromine (Br2) in the presence of KOH (aq) and heat (Δ). This is a reaction of halogenation (bromination) of aromatic compounds, where a nucleophilic substitution occurs at the benzylic position due to the amino group. This type of reaction, when performed with KOH and heating, often leads to the formation of an amide group on the ring, resulting in a phenylamide derivative. Correct Answer:

Choose the correct option.
