A) direct treatment with nitration mixture under reflux
B) using fuming \[HN{{O}_{3}}\]
C) acetylation followed by nitration and subsequent hydrolysis
D) \[KN{{O}_{3}}+conc\,\,HN{{O}_{3}}\]
Correct Answer: C
Solution :
Direct nitration of aniline with \[HN{{O}_{3}}\] gives a complex mixture of mono, di and tri-nitro compounds and oxidation products. If\[N{{H}_{2}}\]group is protected by acetylation and then nitrated, \[p-\]isomer is the main product.You need to login to perform this action.
