Arrange the following in correct order towards S _ N 2 reaction.

Options

  1. AIII > I > IV > II
  2. BIII > IV > I > II
  3. CI > II > III > IV
  4. DI > III > II > IV

Correct answer

A. III > I > IV > II

Step-by-step solution

(a) S _ N 2 reactivity depends on steric crowding at the - carbon and the C - X bond strength. Steric crowding , S _ N 2 reactivity C-X bond strength , S _ N 2 reactivity Thus, the order of reactivity towards S _ N 2 will be :-
