Question

The products A and B formed in the following reaction scheme are respectively

• A.
• B.

  

• C.
• D.

Answer 1

The Correct Option is B

To analyze the reaction sequence, examine the transformations at each step.

Reaction 1 (A): Benzene (C₆H₆) reacts with concentrated nitric acid (HNO₃) and sulfuric acid (H₂SO₄) in a nitration reaction, yielding nitrobenzene:

A = C₆H₅NO₂ (Nitrobenzene).

Reaction 2 (B): Nitrobenzene is subsequently reduced by tin (Sn) in hydrochloric acid (HCl). This process converts the nitro group to an amino group, producing aniline:

B = C₆H₅NH₂ (Aniline).

Therefore, the identified products are: A = C₆H₅NO₂, B = C₆H₅NH₂.
