Nitro group in nitrobenzene is a
- AOrtho director
- ✓Meta director
- CPara director
- DOrtho and para director
✓
Answer
Correct option: B.
Meta director
b
(b) Presence of $ - N{O_2}$ group decreases electron density at $o-$ and $p-$ positions. Hence, incoming electrophile goes to m position. Therefore it is m-directing group.
