Consider the following bromides : Consider the following bromides : The correct order of S_ N 1 reactivity is
The correct order of SN1\mathrm{S}_{\mathrm{N}} 1 reactivity is

Options

  1. AB>C>AB>C>A
  2. BB>A>CB>A>C
  3. CC>B>AC>B>A
  4. DA>B>CA>B>C

Correct answer

A. B>C>AB>C>A

Step-by-step solution

SN1\mathrm{S}_{\mathrm{N}} 1 proceeds via carbocation intermediate, the most stable one forming the product faster. Hence reactivity order for A,B,C\mathrm{A}, \mathrm{B}, \mathrm{C} depends on stability of carbocation created. Consider the following bromides : The correct order of S_ N 1 reactivity is
