7 SN1 vs SN2 Reactions

SN1 vs SN2 Reactions:  Chad breaks down everything the undergraduate organic chemistry student needs to know regarding SN1 and SN2 reactions including substrate effects, nucleophile effects, solvent effects, and what makes a good leaving group.  

You'll also learn "back-side attack" in the SN2 mechanism that leads to inversion of configuration when it occurs at a chiral center, and about the carbocation intermediate in the SN1 mechanism that leads to racemization when the SN1 reaction occurs at a chiral center.  Finally, Chad concludes the lesson working several SN1 vs SN2 examples so that you clearly understand how to distinguish between SN1 and SN2 reactions in terms of the substrate, nucleophile, and solvent and presents an SN1 vs SN2 chart to help students remember how to determine which mechanism is more  likely for nucleophilic substitution.
