Which of the following compounds is most reactive towards nucleophilic aromatic substitution with ?
- A.
- B.
- C.
- D.
Show correct answer & step-by-step solution
Correct answer: D —
Solution
- Nucleophilic aromatic substitution is facilitated by the presence of strong electron-withdrawing groups on the ring.
- These groups stabilize the negatively charged intermediate known as the Meisenheimer complex.
- The reactivity increases with the number of electron-withdrawing groups at ortho and para positions.
- has three nitro groups, providing the maximum stabilization.
- Hence the answer is (D).
