Question

Differentiate between SN¹ and SN² mechanism.

Answer 1

sn1 means first shell
sn2 means 2nd shell

Answer 2

1. For SN1 reactions, the rate determined using the steps are unimolecular in nature. for SN2 reaction, the step followed to determine the rate is bimolecular.

2. SN1 is the two-step mechanism process, whereas the SN2 reaction is a one-step process.

3. During the SN1 reaction, the carbocation gets formed as an intermediate, but, during the SN2 reactions, it wont get formed.
