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...

QUESTION 2 1. Which one of the following statements is true? (HX is either HCl or HBr) Alkynes undergo electrophilic substitution reactions with HX to give halogenated alkenes. Adding an excess of HX to an alkyne gftens times will stop the reaction at the alkene step instead of forming the halogenated alkane. When adding one mole of HX to an alkyne, regioselective Markovnikov addition is observed for the alkene product typically exhibiting trans stereochemistry When adding one mole of HX...
