Alkenes can be converted to alcohols by reaction with mercuric acetate to form a ?-hydroxyalkylmercury(II) acetate compound, a reaction called oxymercuration. Subsequent reduction with NaBH4 reduces the C-Hg bond to a C-H bond, forming the alkyl alcohol, a reaction called demercuration. Draw the structure of the Hg-containing compound and the final alcohol product formed in the following reaction sequence.
