Some \(meta-\) directing substituents in aromatic substitution are given. Which one is most deactivating?
- A \(- COOH\)
- B \(- NO_2\)
- C \(- C\equiv N\)
- D \(- SO_3H\)
Answer & Solution
Correct Answer
(B) \(- NO_2\)
Step-by-step Solution
Detailed explanation
\(-\mathrm{NO}_{2}\) is most deactivating due to - \(\mathrm{I}\) and \(-\mathrm{M}\) effect.
