Amino group is ortho, para directing for aromatic electrophilic substitution. On nitration of aniline with concentrated acids, a good amount of meta nitro aniline is obtained. This is due to Options: A . &nbsp - NH 2 becomes - NH - NO 2 + , which is meta directing B . &nbsp - NH 2 becomes - NH + SO 4 -2 , which is meta directing C . &nbsp - NH 2 becomes - NH 3 + , which is meta directing D . &nbsp In nitration mixture, ortho and para activity of NH 3 group is completely lost

Answer: Option C : C NH 2 is o & p - directing group where as NH 3 + is meta directing group

Amino group is ortho, para directing for aromatic electrophilic substitution. On nitration of aniline with concentrated acids, a good amount of meta nitro aniline is obtained. This is due to

Options:

A . - NH₂ becomes - NH^-NO₂⁺, which is meta directing

B . - NH₂ becomes - NH⁺SO₄^-2, which is meta directing

C . - NH₂ becomes - NH₃⁺, which is meta directing

D . In nitration mixture, ortho and para activity of NH₃ group is completely lost

Answer: Option C
:
C

NH₂ is o & p - directing group where as NH₃⁺ is meta directing group
