Web21 Sep 2024 · To Sum Up: SN1 vs SN2 Mechanisms According to Steric Effects. In short, substitution reactions are simple exchanges of functional groups, such as different halogens. If steric effects allow it, these reactions take place through SN2 bimolecular concerted mechanism, which gives inversion of configuration. If steric hindrance is too … WebIn SN1 reactions, tertiary alcohols are favored. In SN2 reactions, primary alcohols are favored. • Silyl groups can be used to protect alcohols, and fluorine can be used to deprotect. • Tosylates and mesylates are widely used in the protection of alcohols.
