H2SO4 arrow HSO4 -+H+ H++HO-NO2 arrow [.H2O+-NO2]. arrow H2O+NO2 + , Therefore option (A) is correct.

Q. Nitrobenzene can be prepared from benzene by using a mixture of conc. $H N O_{3}$ and conc. $H_{2} S O_{4}$ . In the nitrating mixture $H N O_{3}$ acts as a

Base

Acid

Reducing agent

Catalyst

$H_{2} S O_{4} \to H S O_{4}^{-} + H^{+}$
$H^{+} + H O - N O_{2} \to [H_{2} O^{+} - N O_{2}] \to H_{2} O + N O_{2}^{+}$ ,
Therefore option $(A)$ is correct.
