MCQ

In the mixture of conc. ${H_2}S{O_4}$ and $HN{O_3}$the nitrating species is

A
${N_2}{O_4}$
✓
$NO_2^ + $
C
$N{O_2}$
D
$NO_2^ - $

✓

Answer

Correct option: B.

$NO_2^ + $

b
The process of nitration takes place as below

$HONO _2+2 H _2 SO _4 \rightleftarrows H _3 O ^{+}+2 HSO _4^{-}+\underset{\text { (nitronium ion) }}{ NO _2^{+}}$

So nitrating species is $NO _2^{+}$ ion.
