Which of the following compounds has difficulty in breaking of \(\mathrm{C}-\mathrm{X}\) bond during nucleophilic substitution reaction?
- A o-Nitrochlorobenzene
- B p-Nitrochlorobenzene
- C m-Nitrochlorobenzene
- D 2,4,6-Trinitrochlorobenzene
Answer & Solution
Correct Answer
(C) m-Nitrochlorobenzene
Step-by-step Solution
Detailed explanation
Greater the number of electron withdrawing groups at \(\mathrm{o} / \mathrm{p}\) position, greater is the reactivity towards nucleophilic substitution reaction. Electron withdrawing group at meta position has practically no effect on reactivity. Hence, among the given, m-nitrochlorobenzene has difficulty in breaking of \(\mathrm{C}-\mathrm{X}\) bond during nucleophilic substitution.
