Which of the following will undergo `S_(N)2` most readily ?

A

`CH_(3)-underset(O)underset("||")("C")-CH_(2)-I`

B

`CH_(3)CH_(2)I`

C

`CH_(3)-O-CH_(2)-I`

D

`H_(2)C=CH-CH_(2)-I`

Text Solution

Verified by Experts

The correct Answer is:
A
`S_(N)2` passes through Transition State. The presence of electron withdrawing group at `alpha` - carbon stabilizes the transition state and thus, the reaction rate increases.
