Question

Which of the following compounds will form a significant amount of meta product during the mono-nitration reaction?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is A

Explanation for correct option: A

1. During mono nitration, significant amount of meta product is formed in aniline.
2. As in acidic medium, aniline is protonated to form anilinium ion which is meta directing.

Explanation for incorrect option:

B. In option B, ${\mathrm{NH}}_2$ group is acetylated and hence only forms p-nitro product. Here, nitration reaction is controlled.

C. In option C, Phenols on mono nitration give only ortho and para products because these positions become electron-rich due to the resonance effect.

D. In option D, the ring is protected and hence only ortho and para products are formed.

Therefore, the correct option is A.
