The SN2 reaction - A Nucleophilic Substitution in which the Rate Determining Step involves 2 components.
-SN2 reactions are bimolecular with simultaneous bond-making and bond-breaking steps.
-SN2 reactions do not proceed via an intermediate.
-SN2 reactions give inversion of stereochemistry at the reaction centre.
-Steric effects are particularly important in SN2 reactions.
