WebNucleophilic Substitution (S N 1 S N 2) Nucleophilic substitution is the reaction of an electron pair donor (the nucleophile, Nu) with an electron pair acceptor (the electrophile). An sp 3 -hybridized electrophile must have a leaving group (X) in order for the reaction to take place. Mechanism of Nucleophilic Substitution WebThe actual substitution reaction begins when the leaving group breaks away to generate a 3 o cation. This is the slowest step in the mechanism and is therefore defined as the rate-determining step.Since the R.D.S. only involves one species (the protonated alcohol) this reaction is said to be unimolecular, i.e. SN1..
