Alkenes from alcohols analysis of a
One way to synthesize alkenes is by dehydration of alcohols, a process in which alcohols undergo e1 or e2 mechanisms to lose water and form a double bond the dehydration reaction of alcohols to generate alkene proceeds by heating the alcohols in the presence of a strong acid, such as sulfuric or phosphoric acid, at high temperatures.
