SN2 reaction and conditions required for it
Alkyl halide: SN2 reaction will be slowed down if there exists steric congestion around the carbon atom undergoing the inversion process.
CH3X > RCH2X >> R2CHX >>> R3CX
i.e. we conclude that if there is less congestion then the reaction will be faster.
Leaving group: the leaving group with a full negative charge is always expelled out. As a result the best leaving groups are those that can best stabilize an anion.
Solvent: Surroundings which the solvent surrounds can cause a reaction to go faster or slower. Solvent are of two types:
