Question

Stepwise mechanism of preparation of p-bromoaniline from nitrobenzene

Answer 1

Answer:

4-bromoaniline can be prepared by aniline from several steps. Aniline is an ortho para activator compound like phenol. In 4-bromoaniline bromine atom exist in para position related to the amine group (-NH2 group).

Aniline with liquid bromine reaction

Reaction of aniline and bromine liquid will give 2,4,6-Tribromoaniline. Therefore we have to control the reaction (to stop joining three bromine atoms to benzene ring and stop it by joining only one bromine atom at para position). if we need to prepare 4-Bromoaniline.

Question: Synthesis 4-bromoaniline from benzene. In this reaction you can only use benzene and CH3COCl as organic compounds.
