question_answer

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

A) meta-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 meto-directing. In this reaction the attacking reagent is \[\text{NO}_{\text{2}}^{\text{+}}.\]
