SN1 vs SN2 | Nucleophile, Substrate, Solvent | 7.3 Organic Chemistry

Chad compares and contrasts SN1 and SN2 reactions in this lesson. Chad begins by explaining that vinyl and aryl halides (sp2 halides) are not reactive in both SN1 and SN2 reactions. He then summarizes the differences between the two regarding the substrate, nucleophile, solvent, and the similarity in the leaving group trend. Chad also reminds the student that rearrangements are only possible in SN1 reactions and that while inversion occurs in SN2 reactions, racemization occurs in SN1 reactions. Chad then proceeds to work 7 examples showing how to determine which mechanism, SN1 or SN2, is more likely and then how to predict the product(s) of the substitution reaction. Chad even includes an example of an SN1 reaction involving a carbocation rearrangement and one involving a resonance-stabilized carbonation.
