Acid Catalyzed Hydration-treatment of alkenes with water in the presence of acid catalyst leads to the formation of alcohols. H2SO4/H2O > 150°C Mechanism Major Product Acid catalyzed dehydration goes through a carbocation intermediate. This means that the Markovnikov product is obtained when carbocation rearrangements do not occur. The need for excessively high temperatures makes this reaction of limited use in laboratory synthesis. Oxymercuration - Oxymercuration involves the addition of Hg to the alkene using mercury (II) acetate Hg(OAc) followed by...
