Understand the basic mechanisms of SN1 and SN2 reactions. SN1 reactions are unimolecular nucleophilic substitution reactions, while SN2 reactions are bimolecular nucleophilic substitution reactions.
Recognize that SN1 reactions involve a two-step mechanism: the first step is the formation of a carbocation intermediate, and the second step is the nucleophilic attack on the carbocation.
Identify that SN2 reactions involve a one-step mechanism where the nucleophile attacks the substrate at the same time as the leaving group departs, leading to a concerted reaction.
Consider the stereochemical outcomes: SN1 reactions can lead to racemization due to the planar nature of the carbocation intermediate, while SN2 reactions typically result in inversion of configuration due to the backside attack of the nucleophile.
Evaluate the substrate types: SN1 reactions are more favorable with tertiary substrates due to carbocation stability, whereas SN2 reactions are more favorable with primary substrates due to steric hindrance considerations.
