Question

Identify compound 'A' in the following reaction.

• A. Benzene
• B. Chlorobenzene
• C. Aniline
• D. Cumene

Hint:

The combination of nitration and reduction steps in organic reactions can lead to the formation of amines, such as aniline.

Answer 1

The Correct Option is C

Step 1: Analyzing the reaction.
The given reaction involves the nitration of an aromatic compound, followed by reduction. The nitration reaction involves the use of a mixture of nitric acid (HNO$_3$) and hydrochloric acid (HCl), followed by heating at 273K. The reduction step is done with water and dilute H$_2$SO$_4$. This combination of reactions leads to the formation of an amine group, specifically aniline (C$_6$H$_5$NH$_2$).
Step 2: Analyzing the options.
(A) Benzene: This is incorrect as the reaction produces an amine, not just benzene.
(B) Chlorobenzene: This is incorrect because the reaction does not produce chlorobenzene.
(C) Aniline: This is the correct answer, as the product of the reaction is aniline (C$_6$H$_5$NH$_2$).
(D) Cumene: This is incorrect because the reaction does not involve cumene.
Step 3: Conclusion.
The correct answer is (C) Aniline.
