Nitrobenzene on reaction with conc. `(HNO_3)/(H_2SO_4)` at `80-100^@C` forms which one of the following products?

Options

A. 1,2-dinitrobenzene
B. 1,3-dinitrobenzene
C. 1,4-dinitrobenzene
D. 1,2,4-trinitrobenzene

Answer

B

Explanation

`NO_2` group bQing electron withdrawing reduces electron density at o/ p positions. Hence, meta-position becomes electron rich on which the electrophile (nitronium ion) attacks during nitration.
`2HNO_3 + H_2SO_4 to H_2NO_3^(+) + HSO_4^(-) + H_2O + underset"Electrophile"(NO_2^+)`
