2-methyl-2-hexanol was prepared by reacting an alkene with elther hydroboration-oxidation or oxymercuration-reduction. Draw the structure of the alkene that was used to prepare the alcohol in highest yield. - You do not have to consider stereochemistry. - Indicate the method of preparation by drawing either BH3 (for hydroboration-oxidation), or Hg (for oxymercuration-reduction), in a separate s - If there is more than one alkene that can be used for a given method, draw all of them. - If either hydroboration-oxidation or oxymercuration-reduction can be used, fust give the structures for one method. - Separate structures with + signs from the drop-down menu. Dihydropyran is synthesized by treating tetrahydrofurfuryl alcohol with an arenesulfonic acid, Ar5O3H. Oraw curved arrows to show the movement of electrons in this step of the reaction mechanism. H2O
