Aromatic Compounds Containing Nitrogen - Result Question 32
####33. When nitrobenzene is treated with
(a) the electron density on meta carbon is more than that on ortho and para positions
(b) the intermediate carbonium ion formed after initial attack of
(c) loss of aromaticity when
(d) easier loss of
Show Answer
Answer:
Correct Answer: 33. (a,b)
Solution:
- Nitro group withdraws electrons more from ortho/para position than from meta position. Also the
-complex formed from meta attack is less destabilised than from ortho/para positions.
Nitro group not destabilising the positive charge by resonance.
Nitro group destabilises the positive charge directly by resonance, less stable
Similar phenomenon is observed with ortho attack.
