Nitrobenzene on reaction with conc. HNO3/H2SO4\mathrm{HNO}_3 / \mathrm{H}_2 \mathrm{SO}_4 at 80−100∘C80-100^{\circ} \mathrm{C} forms which one of the following products?Nitrobenzene on reaction with conc. HNO_3 / H_2 SO_4 at 80-100^ C forms which one of the following products?

Options

  1. A1,2-dinitrobenzene
  2. B1,3-dinitrobenzene
  3. C1,4-dinitrobenzene
  4. D1,2,4-trinitrobenzene

Correct answer

B. 1,3-dinitrobenzene

Step-by-step solution

NO2\mathrm{NO}_2 group being electron withdrawing reduces electron density at output positions. Hence, now the meta-position becomes electron rich on which the electrophile (nitronium ion) attacks during nitration. Nitrobenzene on reaction with conc. HNO_3 / H_2 SO_4 at 80-100^ C forms which one of the following products?
