Aniline is protected as acetanilide before nitration to obtain 4-nitroaniline. Which of the following is NOT a reason for this?

  1. Ait prevents oxidation of the amino group by nitric acid
  2. Bit prevents formation of the meta-directing anilinium ion
  3. Cacetylation makes the ring more strongly activated than aniline, speeding the reaction
  4. Dit moderates the activating effect of nitrogen on the ring

Answer: C

The acetamido group is less activating than because the nitrogen lone pair is also delocalised toward the carbonyl group. So acetylation reduces, not increases, ring activation. The other three statements are genuine advantages of protection.
