Consider the following bromides:

The correct order of `S_(N^1)` reactivity is

A

`A gt B gt C`

B

`B gt C gt A`

C

`B gt A gt C`

D

`C gt B gt A`

Text Solution

Verified by Experts

The correct Answer is:
B
`S_N` 1 reaction rate depends upon the stability of the carbocation formed in the rate determining step (RDS). Compound (B), forms a `2^@` allylic carbocation which the most stable , the next stable carbocation is formed from (C), it is a `2^@` carbocation , (A) forms the least stable `1^@` carbocation. The order of reactivity is thus :
