MCQ
The electrophile in the nitration of benzene is
- ✓$NO_2^ + $
- B$N{O_2}$
- C$N{O^ + }$
- D$NO_2^ - $
✓
Answer
Correct option: A.
$NO_2^ + $
a
(a) $NO_2^ \oplus $ is produced when conc.$HN{O_3}$ reacts with conc.${H_2}S{O_4}$.
(a) $NO_2^ \oplus $ is produced when conc.$HN{O_3}$ reacts with conc.${H_2}S{O_4}$.
$HN{O_3} + {H_2}S{O_4} \to HSO_4^ - + NO_2^ \oplus + {H_2}O$
