carbocation–molecule pair (with a secondary isotope effect of 1·54), which either undergoes nucleophilic attack by a solventmolecule (with a secondary isotope effect of ca 1), or is dehydronated (isotope effect ca 2·8) by the leaving group or by the solvent. The ion-moleculepair shows very low selectivities. Thus, in 50 vol.% acetonitrile in water, an acetonitrile molecule is as efficient as a watermolecule as a
