Bromination of aniline gives 2, 4, 6-tribromoaniline; whereas the nitration of aniline with mixed acids gives m-nitroaniline. In the case of nitration, the m derivative is formed because
1
In the presence of strong acids, the amino group is protonated to \(\rm -\stackrel+NH_3 \), which is m-orienting
2
m-nitroaniline is theromodynamically more stable than the ortho and para-isomers
3
Nitro group cannot enter ortho and para positions, due to steric factor
4
The mechanism for bromination and nitration are different
