If Aniline is treated with ( 1: 1 ) mixture of conc. ( HNO ₃ ) and con. ( H 2 SO ₄, p )-nitroaniline and ( m ) - nitroaniline are formed nearly in equal amounts. This is due to
Options
- A( m & p ) directing property of ( - NH ₂ ) group.
- Bisomerization of some p-nitroaniline into m-nitroaniline.
- Cm-directing property of ( - NH ₂ ) group.
- Dprotonation of ( - NH ₂ ) which causes deactivation of benzene ring.
Correct answer
D. protonation of ( - NH ₂ ) which causes deactivation of benzene ring.
Step-by-step solution
(D) In presence of acid aniline gets protonated to anilinium ion which is meta directing.
