Dehydration of 2-Methylcyclohexanol Formal Report
kene. This type of reaction requires an alcohol, an acid catalyst and heat. Generally strong concentrated acids, like sulfuric acid and phosphoric acid, are used as the acid catalyst.The acid catalyst ... can form a more stable molecule. An E2 mechanism means that the reaction is an elimination and the rate-determining step is bimolecular, two species are involved in one step of the mechanism. If the ...
