These reactions can occur by a range of mechanisms. SN2 and SN1 are the extremes. The SN2 reaction occurs in a single step. The nucleophile enters as the leaving group — usually a halide ion — departs. The reaction displays second-order kinetics; its rate is proportional to the concentration of the organo-halide and the nucleophile. reading ahead resources
