Q13 · 1 mark · Assertion-reasonCompetency-basedAmines

Assertion (A): Nitration of aniline gives significant amount of meta derivative.
Reason (R): is ortho and para directing and highly activating group.

Select the most appropriate answer from the options given below:

  1. (A)Both A and R are true, and R is the correct explanation of A.
  2. (B)Both A and R are true, and R is not the correct explanation of A.
  3. (C)A is true but R is false.
  4. (D)A is false but R is true.

Hints

Open one hint at a time and try again before the next.

Hint 1

Think about what happens to aniline in a strongly acidic medium.

Hint 2

Decide which directing group is actually present during nitration.

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. A is true. In the strongly acidic nitrating mixture, aniline is protonated to the anilinium ion, , which is meta directing. About 47% m-nitroaniline is formed.

  2. R is true as a general fact: free –NH₂ is an activating, o/p-directing group. However, it does not explain why the meta product forms. So the answer is B.

    1 mark

Answer: Option (B)

Where the marks are

  • Both statements true; meta product is due to the anilinium ion, so R is not the explanation (1 mark)
