Question: Benzene on nitration gives nitrobenzene in presence of $\mathrm{HNO}_{3}$ and $\mathrm{H}_{2} \mathrm{SO}_{4}$ mixture, where :
both $\mathrm{H}_{2} \mathrm{SO}_{4}$ and $\mathrm{HNO}_{3}$ act as a bases
$\mathrm{HNO}_{3}$ acts as an acid and $\mathrm{H}_{2} \mathrm{SO}_{4}$ acts as a base
both $\mathrm{H}_{2} \mathrm{SO}_{4}$ and $\mathrm{HNO}_{3}$ act as an acids
$\mathrm{HNO}_{3}$ acts as a base and $\mathrm{H}_{2} \mathrm{SO}_{4}$ acts as an acid
Correct Option: , 4
Solution:
