Verified step by step guidance

Understand the difference between SN1 and SN2 reactions: SN1 reactions are unimolecular nucleophilic substitution reactions, while SN2 reactions are bimolecular nucleophilic substitution reactions.

Consider the factors affecting reaction rates: SN2 reactions are typically faster because they involve a single concerted step where the nucleophile attacks the substrate at the same time as the leaving group departs.

Analyze the steric hindrance: SN2 reactions are faster in less hindered substrates because the nucleophile can more easily approach the electrophilic carbon.

Evaluate the role of the nucleophile: In SN2 reactions, a strong nucleophile is required to attack the substrate effectively, which contributes to the faster reaction rate.

Compare with E1 and E2 reactions: E2 reactions are also bimolecular and can be fast, but they involve elimination rather than substitution. E1 reactions, like SN1, are unimolecular and generally slower due to the formation of a carbocation intermediate.
