BIMOLECULAR NUCLEOPHILIC SUBSTITUTION REACTIONS (SN2)
Nucleophilic substitution reactions that involve two molecules in the rate determining step and complete in one step are known as bimolecular substitution reactions.
=> The rate of reaction is dependent upon the concentration of both the substrate and the nucleophile
=> Inversion of stereochemistry takes place (Walden Inversion)
=> The reaction goes through a single transition state. No intermediates are involved.
=> The rate is also affected by the choice of solvent, structure of substrate, and the nucleophilicity of nucleophile.
