The correct order for increasing reactivity towards \(S_N 1\) substitution for the following compounds is
\(\begin{array}{ll}\text { 1. } \mathrm{CH}_3 \mathrm{CH}_2 \mathrm{Br} & \text { 2. } \mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}(\mathrm{Br}) \mathrm{CH}_3 \\ \text { 3. } \mathrm{CH}_2=\mathrm{CHBr} & \text { 4. } \mathrm{CH}_3-\mathrm{CH}(\mathrm{Br}) \mathrm{CH}_3\end{array}\)

  1. A \(1 < 4 < 3 < 2\)
  2. B \(4 < 1 < 2 < 3\)
  3. C \(3 < 1 < 2 < 4\)
  4. D \(3 < 1 < 4 < 2\)

Answer & Solution

Correct Answer

(D) \(3 < 1 < 4 < 2\)

Step-by-step Solution

Detailed explanation

\(\mathrm{S}_{\mathrm{N}} \mathrm{l}\) reaction is a two step reaction in which greater the stability of carbocation, greater will be its formation from alkyl halide and faster will be the rate of reaction. As, the stability of carbocations formed is in the order.…
