PDF SN1 and SN2 Reactions - Illinois Institute of Technology The S N 2 Reaction Notes: In the SN2 reaction, the nucleophile attacks from the most δ+ region: behind the leaving group. This is called a back-side attack. This back-side attack causes an inversion (study the previous slide): after the leaving group leaves, the other substituents shift to make room for the newly-bonded nucleophile, changing the stereochemistry of the molecule.
