In electrophilic aromatic substitution reaction, the nitro group is meta directing because it
In electrophilic aromatic substitution reaction, the nitro group is meta directing because it
Show Hint
Deactivating groups (like $-NO_2$, $-CN$) are meta-directing because they deplete ortho/para density.
Updated On: Apr 10, 2026
- decreases electron density at ortho and para positions
- decreases electron density at meta position
- increases electron density at meta position
- increases electron density at ortho and para positions
Show Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Nature of Nitro Group
The nitro group ($-NO_2$) is a strong electron-withdrawing group due to resonance and inductive effects.
Step 2: Impact on Ring
It withdraws electrons specifically from the ortho and para positions. This significantly decreases electron density at those sites.
Step 3: Directing Effect
As a result, the meta position has a relatively higher electron density compared to ortho and para, making it the preferred site for electrophilic attack.
