During the nitration of aniline, the amino group is protected by
1 Converting it to \(\mathrm{NO}_{2}\) group
2 Converting it to Carboxylic group
3 Acylation
4 Benzoylation
Explanation:
\(-\mathrm{NHCOCH}_{3}\) is less active than \(\mathrm{NH}_{2}\)

Consider the following reaction, \(X\) is
1 benzoic acid
2 salicylic acid
3 phenol
4 aniline
Explanation:
CHXII13:AMINES
324142
Aniline does not undergo
1 Friedel-Craft reaction
2 Bromination
3 Nitration
4 Sulphonation
Explanation:
Anhy. \(\mathrm{AlCl}_{3}\) reacts with aniline. So, electrophile will not be generated. Hence , aniline does not undergo Friedel - craft's reaction.

Statement A : Nitration of aniline can be conveniently done by protecting the amino group by acetylation. Statement B : Acetylation increases the electron- density in the benzene ring
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Acetylation decreases the electron-density in the benzene ring thereby preventing oxidation.
