SN2 Reaction Mechanisms in Organic Chemistry: Transition States and Solvent Effects
The SN2 (Substitution Nucleophilic Bimolecular) reaction is a concerted mechanism wherein bond formation and bond cleavage occur simultaneously via a single transition state, resulting in the inversion of stereochemical configuration at the chiral center. The kinetics of this second-order process are governed by concentrations of both the substrate and nucleophile, while reactivity is modulated strictly by steric accessibility—favoring methyl > primary > secondary substrates and excluding tertiary or allylic/vinylic halides—and solvent polarity effects that influence nucleophilicity in protic versus aprotic environments.
