Q. Nitrobenzene on reaction with conc. HNO₃/H₂SO₄ at 80–100°C forms which one of the following products?
A) 1,2-Dinitrobenzene
B) 1,3-Dinitrobenzene
C) 1,4-Dinitrobenzene
D) 1,2,4-Trinitrobenzene
Explanation
[Solution from source] –NO₂ is a strong deactivating, meta-directing group, so the second nitro group enters the meta position, giving 1,3-dinitrobenzene. Ortho/para dinitro products would need an ortho/para-directing group. Answer (2).
