SN2 Inversion
Backside attack inverts the stereocenter in one step.
E2 of Alkyl Halides
Concerted anti-periplanar loss of H and X gives an alkene.
SN1 Solvolysis
The substrate ionizes to a carbocation, then solvent attacks.
E1 Elimination
A carbocation forms, then loss of a beta-proton gives the alkene.
SN1 Stereochemistry
The planar cation is attacked from both faces, giving racemic product.
SN2 with Tosylate
A tosylate leaving group is displaced with inversion.
SN1 with Rearrangement
A hydride or alkyl shift builds a more stable cation.
E1 with Rearrangement
The cation rearranges before eliminating to an alkene.
SN2 of Alcohols
A protonated alcohol is displaced by halide via SN2.
SN1 of Alcohols
A protonated alcohol ionizes, then halide traps the cation.
