  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.
