What is the role of `HNO_(3)` in the nitrating mixture used for nitration of benzene?

Text Solution

Verified by Experts

`HNO_(3)` acts as a base in the nitrating mixture (conc. `HNO_(3)+conc.H_(2)SO_(4)`). `H_(2)SO_(4)` acts on `HNO_(3)` to generate the electrophile, `NO_(2)^(+)` (nitronium ion).
