    experiment‚ the carbocation intermediate forms as the alcoholic hydroxyl group is protonated with acid‚ and dihydrogen oxide leaves. After this unimolecular dissociation step‚ a proton from one of the adjacent carbons is captured to reform the acid catalyst‚ and the elimination reaction is complete with the formation of the double bond. Water is distilled out of the reaction to promote a high yield of 4-methylcylohexene. By removing water‚ the reaction is forced in the forward direction due to Le Châtelier’s
