Question

Consider the following compounds :

The correct order of reactivity towards SN₂ reaction :

(A) I > III > II

(B) II > III > I

(C) II > I > III

(D) III > I > II

Answer 1

Option : (C) II > I > III

1° halide shows SN2 reaction very fast than 2°.

Here,

(II) halide is 1°, and (I) is 2°, chlorobenzine cannot shows SN₂ reaction.

Therefore,

Correct order will be II > I > III
