Why does acetylation of the -NH 2 group of aniline reduce its activating effect?
Options
- AAcetylation increases the electron density on the nitrogen atom, leading to decreased activation.
- BAcetylation enhances the resonance stabilization of the amino group, weakening its activating effect.
- CBecause the lone pair on the nitrogen atom is in conjugation with the carbonyl group in acetylated aniline. As
- DAcetylation decreases the steric hindrance around the amino group, making it less reactive.
Correct answer
C. Because the lone pair on the nitrogen atom is in conjugation with the carbonyl group in acetylated aniline. As
Step-by-step solution
Correct Option is : (C) Because the lone pair on the nitrogen atom is in conjugation with the carbonyl group in acetylated aniline. As a result, the lone pair of electrons on nitrogen is less available for donation to benzene ring by resonance
