The key difference between the S N 2 and E2 reactions is that the nucleophile in the S N 2 mechanism attacks the carbon connected to the leaving group (ɑ-carbon) while in E2, the base attacks one of the β-hydrogens. The result is a replacement of the leaving group with a nucleophile, in the S N 2, and a newly-formed π bond in the E2 reaction.IUPAC Namer. Mechanism Solver 🧪. Orbital Hybridization Solver 🧪.
