Consider the following bromides : The correct order of S _ N 1 reactivity is

Options

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

Correct answer

A. B>C>A

Step-by-step solution

S _ N 1 proceeds via carbocation intermediate, the most stable one forming the product faster. Hence reactivity order for A , B , C depends on stability of carbocation created.
