Hints

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

Hint 1

What happens to in strong acid?

Hint 2

The anilinium ion is meta-directing.

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. In the strongly acidic nitrating mixture, aniline is protonated to the anilinium ion, which is meta-directing. This gives a large amount of meta product.

  2. Direct nitration gives 51% para, 47% meta and 2% ortho products. Option (C).

    1 mark

Answer: Option (C)

Where the marks are

  • Gives the 51% p, 47% m, 2% o distribution (1 mark)
