Popis:	The secondary deuterium isotope effect is reported for the decomposition of benzyl-α-d2-phenyldimethylammonium bromide in both chloroform and acetone solvent, over a temperature range of 25 to 30°. The magnitudes of the rate ratios are compared to literature values for SN1 reactions, from which it is concluded that the mechanism of the decomposition involves a carbonium ion or ion-pair. The variation of the isotope effect with solvent is rationalized in terms of specific solvent interaction with the benzyl group.
