The correct order of reactivity for reactions involving cleavage of \(\mathrm{C}-\mathrm{Cl}\) bond in following compounds is
- A I \(\gt\) II \(\gt\) III
- B II \(\gt\) III \(\gt\) I
- C III \(\gt\) I \(\gt\) II
- D III \(\gt\) II \(\gt\) I
Answer & Solution
Correct Answer
(D) III \(\gt\) II \(\gt\) I
Step-by-step Solution
Detailed explanation
Greater the number of electron withdrawing groups \(\left(-\mathrm{NO}_2\right)\) at \(\mathrm{o} / \mathrm{p}\) position, greater is the reactivity. Hence, 2,4,6-trinitrochlorobenzene has the highest reactivity.
