Question

The nitration of a compound is due to the?

• A. $N{O}_2$
• B. $N{O}_3$
• C. $NO$
• D. $N{O}_2^{+}$

Answer 1

The correct option is D

$N{O}_2^{+}$

The process of nitration takes place as below

$HON{O}_2+2H_{2}S{O}_4\rightleftharpoons$ $H_3{O}^{+}+2HS{O}_4^{-}+N{O}_2^{+}$

(nitronium ion)

The electrophile responsible for nitration is

$N{O}_2^{+}$ ion.
