Why must dehydration reactions of alcohols be carried out under acid catalysis? 1) the hydroxide group is a poor leaving group and must be protonated to generate a better leaving group. 2) the hydroxide group is a great leaving group and does not need to be protonated to generate a better leaving group. 3) the acid isn't necessary for the reaction. 4) None of these are correct answers.

14-71 The mechanism of the acid-catalyzed dehydration of an alcohol to an alkene is the reverse of the acid- catalyzed hydration of an alkene. The dehydration mechanism occurs by the following three steps. Step 1: Add a proton. Step 2: Break a bond to form stable molecules or ions. Step 3: Take away a proton. These three steps are illustrated here by the dehydration of 2-butanol to give 2-butene. Use curved arrows to show the flow of electrons in each step; that is, show how each bond-making or bond-breaking step occurs. H I + Step 3: CH3—CH—CH—CH3 CH3—CH=CH—CH3 + H + 2-butene
