Question

The final product C, obtained in this reaction, would be:

• A.
• B.
• C.
• D.

Answer 1

The Correct Option is C

Let's analyze the reaction sequence given in the problem to determine the final product C.

1. **Acetylation Reaction**: The starting compound is p-toluidine (p-methyl aniline). When it reacts with acetic anhydride (\( \text{Ac}_2\text{O} \)), acetylation of the amino group occurs, leading to the formation of N-acetyl-p-toluidine (Compound A).

2. **Bromination Reaction**: Compound A undergoes bromination in the presence of bromine (\( \text{Br}_2 \)) and acetic acid (\( \text{CH}_3\text{COOH} \)), targeting the ortho and para positions relative to the acetylated amino group. Since the para position already has a substituent, bromination occurs at the ortho position. This results in the formation of 2-bromo-N-acetyl-p-toluidine (Compound B).

3. **Hydrolysis Reaction**: Finally, compound B undergoes hydrolysis in the presence of an acidic medium (\(\text{H}_2\text{O}/\text{H}^+\)). This reaction removes the acetyl group, regenerating the amino group, and results in the formation of 2-bromo-p-toluidine (Compound C).

Therefore, the final product C is 2-bromo-p-toluidine.
