Question

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

• A. meta-dinitrobenzene
• B. ortho-dinitrobenzene
• C. para-dinitrobenzene
• D. 1, 3, 5-trinitro benzene

Answer 1

Answer: (A)

meta-dinitrobenzene

Answer 2

Nitrobenzene on nitration gives m-dinitro benzene, as $- NO _{2}$ group is meta-directing. In this reaction the attacking reagent is $NO _{2}^{-}$.
