Draw a mechanism for the following: 4. If an alcohol is used instead of water, ethers are produced. Draw a mechanism for the following: 5. Many reactions are intramolecular. Here the reactants are both in the same molecule. Draw a mechanism to explain the following: 6. Mercury is toxic and used only when necessary for synthesis. In class we learned that the oxy-­‐
mercuration/demercuration scheme could be used to give products of alkene hydration without rearrangements. For each of the following reactions, give the product of each and indicate the product you would obtain by simple hydration in aqueous acid. 7.
