Question

Nitrobenzene on reaction with conc. $HN{O}_3/H_{2}S{O}_4$ at $80-{100}^{\circ }C$ forms which one of the following products ?

• A. $\text{1, 2 -Dinitrobenzene}$
• B. $\text{1, 4 -Dinitrobenzene}$
• C. $\text{1, 2, 4- Trinitrobenzene}$
• D. $\text{1, 3 -Dinitrobenzene}$

Answer 1

The correct option is D $\text{1, 3 -Dinitrobenzene}$


Mixture of $\left[ConcHN{O}_{3}conc{H}_{2}S{O}_4\right]$ gives ${}^{+}N{O}_2$ which acts as electrophile and in nitrobenzene $-N{O}_2$ group is a meta directing group so nitronium ion attacks at meta position.

Hence, option (c) is correct.
