WebAlcohols to alkenes: Brønsted acid catalysis Acids have been used for many years to dehydrate alcohols to alkenes. Primary alcohols undergo dehydration reactions to form alkenes via the concerted E2 mechanism43 due to the instability of primary carbocations,9 however, the pathways for the dehydration of secondary alcohols are not as clear.43 WebDehydration of Alcohols Reaction type: 1,2- or β-Elimination Summary. When heated with strong acids catalysts (most commonly H 2 SO 4, H 3 PO 4), alcohols typically undergo a 1,2-elimination reactions to generate an alkene and water.; Also known as dehydration since it involves the removal of a molecule of water.; Alcohol relative reactivity order : 3 …
