Which of the following is the correct order of decreasing `S_(N^(2))` reactivity ?

A

`R_(2)CHX gt R_(3)CX gt RCH_(2)X`

B

`RCH_(2)X gt R_(3)CX gt R_(2)CHX`

C

`RCH_(2)X gt R_(2)CHX gt R_(3)CX`

D

`R_(3)CX gt R_(2)CHX gt RCH_(2)X`

Text Solution

Verified by Experts

The correct Answer is:
C
Reactvity decreases as the stearic hindrance i.e., number of alkyl substitutents at `alpha` carbon increases.
