Consider the following sequence of reactions
`C_(6)H_(5)NH_(2) underset("heat")overset(Ac_(2)O)(to) A underset({:("Conc".H_(2)SO_(4)),(0-a5^(@)C):})overset("conc".HNO_(3))(to) B underset("major")(B) underset("heat")overset(aq.H_(2)SO_(4))(to) underset(("major")(C )` .

A

o-nitroaniline

B

2,4,6-trinitroaniline

C

p-nitroacetanilide

D

p-nitroaniline

Text Solution

Verified by Experts

The correct Answer is:
D
First step involves acetylation of aniline to yield acetanilide Second step involves nitration of acetanilide to yield mainly p-nitroacetanilide which on acid hydrolysis followed by addition of an alkali gives p-nitroaniline
