Arrange the following bromides in the order of reactivity in undergoing \(\mathrm{S}_{\mathrm{N}} 1\) reaction.
- A i \(>\) iii \(>\) ii \(>\) iv
- B iv \(>\) ii \(>\) iii \(>\) i
- C i \(>\) ii \(>\) iii \(>\) iv
- D ii \(>\) iv \(>\) iii \(>\) i
Answer & Solution
Correct Answer
(A) i \(>\) iii \(>\) ii \(>\) iv
Step-by-step Solution
Detailed explanation
As stability of carbocation is in order \(\rightarrow 3^{\circ}>20>1^{\circ}\), so the order of \(S_N 1\) reaction in alkyl halide. (i) \(3^{\circ}>2^{\circ}>1^{\circ}\) So, the correct order is \(i i i>i i>i v\).
