Which of the following si most reactive toward `S_(N^(2))` reaction ?

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
D
4-nitrobenzyl chloride is likely to react by the `S_N2` mechanism as the strongly electron-withdrawing nitro group would destabilize the carbocation intermediate of the `S_N1` mechanism, a benzylic chloride the disfavours the `S_N1` mechanism.
