Question

Quizplus · Accepted Answer

The rate determining step in the acid-catalyzed dehydration of alcohols is usually the protonation of the hydroxyl group by the acidic catalyst. In the case of 3,3-dimethyl-2-butanol, the protonation of the hydroxyl group (step B) is the slowest step and therefore the rate determining step.
