Benzene on nitration gives nitrobenzene in presence of

{HNO}_{3}

and

{H}_{2}{SO}_{4}

mixture, where: Benzene on nitration gives nitrobenzene in presence of HNO _ 3 and H _ 2 SO _ 4 mixture, where:

Benzene on nitration gives nitrobenzene in presence of HNO _ 3 and H _ 2 SO _ 4 mixture, where:

Options

Aboth ${H}_{2}{SO}_{4}$ and ${HNO}_{3}$ act as a bases
B ${HNO}_{3}$ acts as an acid and ${H}_{2}{SO}_{4}$ acts as a base
Cboth ${H}_{2}{SO}_{4}$ and ${HNO}_{3}$ act as an acids
D ${HNO}_{3}$ acts as a base and ${H}_{2}{SO}_{4}$ acts as an acid

Correct answer

D. ${HNO}_{3}$ acts as a base and ${H}_{2}{SO}_{4}$ acts as an acid

Step-by-step solution

Reagent for nitration of Benzene

$\mathop{{H}_{2}{SO}_{4}}_{\left(Acid\right)} + \mathop{{HNO}_{3}}_{\left(Base\right)} ⇄ {HSO}_{4}^{⊖} + \overset{⊕}{H}2{NO}_{3}$

${H}_{2}{NO}_{3} ⇄ {H}_{2}O + \overset{⊕}{N}{O}_{2}$

Benzene on nitration gives nitrobenzene in presence of HNO _ 3 and H _ 2 SO _ 4 mixture, where:
