Step 1
This reaction is actually referred to as acid-catalyzed hydration. In this reaction, the alkene acts as a nucleophile and reacts with the water molecule, which is acting as an electrophile. The acid catalyst helps to speed up the reaction. The end result of this Show more…

The mechanism of the acid-catalyzed dehydration of an alcohol to an alkene is the reverse of the acidcatalyzed 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.
