![]() ![]() Handle all solutions with care and dispose of all waste properly. The products of these reactions are lachrymators and moderately toxic. Work with the concentrated bromine water solution only in the hood. Br 2 is a corrosive strong oxidant and very toxic. ![]() Proposed mechanism for the reaction of Br 2 with acetone. Reaction of Br 2 with acetone to give a-bromoacetone, Br – and H +. Therefore, the rate of bromination of deuterated acetone will be measured to determine if there is a kinetic isotope effect, and thus provide further evidence for the proposed mechanism.įigure 1. In addition, because this mechanism involves the breaking of a C-H bond it is expected that it should display a kinetic isotope effect when D is substituted for H. 1 In this exercise you will test whether this proposed mechanism is consistent with the experimental rate law by first experimentally determining the rate law using the isolation method (click here to review kinetics) and deriving the rate law predicted by this mechanism. 2 is a proposed mechanism for this reaction. Under acidic conditions ketones react with halogens to give substitution at the alpha-carbon, as shown in Fig. Adapted from an Exercise developed by the Physical Chemists at the University of Kansas by J. ![]()
