MCQ
The nitration of a compound is due to the
  • A
    $N{O_2}$
  • B
    $N{O_3}$
  • C
    $NO$
  • $NO_2^ + $

Answer

Correct option: D.
$NO_2^ + $
d
(d) The process of nitration takes place as below

$HON{O_2} + 2{H_2}S{O_4}$ $ \rightleftharpoons $ ${H_3}{O^ + } + 2HSO_4^ - + \mathop {NO_2^ + }\limits_{({\rm{nitronium ion}})} $

The electrophile responsible for nitration is $NO_2^ + $ ion.
