Which of the following compounds has difficulty in breaking the C - Cl bond?

Options

  1. Ao-Nitrochlorobenzene
  2. Bm-Nitrochlorobenzene
  3. Cp-Nitrochlorobenzene
  4. D2,4,6 -trinitrochlorobenzene

Correct answer

B. m-Nitrochlorobenzene

Step-by-step solution

Greater the number of electron withdrawing groups at o/p position, greater is the reactivity of haloarenes towards substitution of halogen atom. Electron withdrawing group at meta position has practically no effect on reactivity. Hence breaking the C - Cl bond is the most difficult in m -nitrochlorobenzene.
