In order to explain this mechanism's normal result, Winstein has proposed that the presence of ion pairs hinders complete racemization from it. Strong leaving groups like tosylates increase the rate of reactions of this type, but nucleophile concentration changes have no effect on it. Proceeding in two steps, it works best with tertiary alkyl halides and proceeds more rapidly in aprotic solutions. Its rate determined by the dissociation of the substrate, which results in the formation of a carbocation and is unimolecular. FTP, identify this reaction mechanism; a first-order nucleophilic substitution.
