alkenes can be converted to alcohols by reaction with mercuric acetate to form a β‑hydroxyalkylmercury(ii) acetate compound, a reaction called oxymercuration. subsequent reduction with nabh4nabh4 reduces the c–hgc–hg bond to a c–hc–h bond, forming the alkyl alcohol, a reaction called demercuration. draw the structure of the hghg ‑containing compound and the final alcohol product formed in the reaction sequence.
