http://crab.rutgers.edu/~alroche/Ch17.pdf WebIf we take a sample of ordinary benzene, C 6 H 6, and a sample of deuterated benzene, C 6 D 6, we can measure how quickly they each undergo a bromination reaction. Very often, a reaction that involves C-H bond cleavage will slow down if a C-D bond is involved. This outcome is observed in E2 eliminations, for instance.
