WebUnimolecular dehydration of C 3 -C 4 alcohols follows the same mechanism as that for ethanol and involves inhibition by dimers. Deuterated alcohols show a primary kinetic isotope effect for unimolecular dehydration, implicating cleavage of a C-H bond (such as the C β -H bond) in the rate-determining step for olefin formation on γ-Al 2 O 3. WebData on the reaction mechanism shows us that the reaction occurs in two steps: Step 1: Step 2: So we see that each elementary step is bimolecular and not termolecular. Notice that the colliding molecules may be the same (as in step 1 above) or different (as in step 2 above).
