Nitration of nitrobenzene at \[125{}^\circ C\] with mixed acids gives

A)  meto-dinitrobenzene

B)  ortho-dinitrobenzene

C)  para-dinitrobenzene

D)  1, 3, 5-trinitro benzene

Correct Answer: A

Solution :

 Nitrobenzene    on    nitration    gives \[m-\]dinitro benzene as \[-N{{O}_{2}}\] group is meta-directing. In this reaction the attacking reagent is \[\text{NO}_{\text{2}}^{\text{+}}\text{.}\]
