Question

An organic compound (A) on reduction gives compound (B). (B) on treatment with CHCl\(_3\) and alcoholic KOH gives N-methyl aniline. The compound A is

• A. Methylamine
• B. Aniline
• C. Nitromethane
• D. Nitrobenzene

Hint:

The reduction of nitrobenzene leads to aniline, which undergoes further reactions, such as methylation, to form N-methyl aniline.

Answer 1

The Correct Option is D

Step 1: Analyze the reaction sequence.
Compound A must be nitrobenzene, as its reduction and subsequent treatment with CHCl\(_3\) and alcoholic KOH lead to the formation of N-methyl aniline.
Step 2: Conclusion.
Thus, the compound A is nitrobenzene.
Final Answer: \[ \boxed{\text{Nitrobenzene}} \]
