Which of the following compounds has difficulty in breaking of C - X bond during nucleophilic substitution reaction?

Options

  1. Ao-Nitrochlorobenzene
  2. Bp-Nitrochlorobenzene
  3. Cm-Nitrochlorobenzene
  4. D2,4,6-Trinitrochlorobenzene

Correct answer

C. m-Nitrochlorobenzene

Step-by-step solution

Greater the number of electron withdrawing groups at o / 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 C - X bond during nucleophilic substitution.
