The rate of attack of an electrophile is least when \(\mathrm{X}\) in the given compound is
- A \(-\mathrm{NO}_2\)
- B \(-\mathrm{CH}_3\)
- C \(-\mathrm{OH}\)
- D \(-\mathrm{NH}_2\)
Answer & Solution
Correct Answer
(A) \(-\mathrm{NO}_2\)
Step-by-step Solution
Detailed explanation
\(-\mathrm{OH},-\mathrm{CH}_3\) and \(-\mathrm{NO}_2\) are activating groups. They activates the benzene ring for the attack by an electrophile. \(-\mathrm{NO}_2\) is a deactivating group. Due to its strong -I effect, it reduces the electron density in the benzene ring which…
