WebThis is a key difference between the S N 1 and S N 2 mechanisms. In the S N 1 reaction the nucleophile attacks after the rate-limiting step is over, whereas in S N 2 the nucleophile forces off the leaving group in the limiting step. WebSn1 and Sn2 reactions may at first seem paradoxical based on their numbers. Considering the number of steps involved, these reactions seem backward. ... The order of reactivity here is exactly opposite to the SN2 reaction order. Effects of leaving group An SN1 reaction is also accelerated by a good leaving group. Leaving groups are crucial for ...
