Unformatted text preview: Experiment #2 A Dehydrogenation/Hydrogenation Reaction In this experiment, carvone, a ketone monoterpene, was reacted with Pd/C and heat. If dehydration/ hydration occurred the molecule, 2-methl-5-isopropylphenol should be generated (Lab Manual, 83T) Hydrogenation is a method where hydrogen is transferred to another molecule and dehydration is removing hydrogen from a molecule to obtain an aromatic compound. An amount of .14 mL of carvone was reacted with .03 g of Pd/ C, a black powder. This reaction was heated for an hour and spotted every 15 minutes. Four TLC were produced for every 15 minutes with three lanes. The first spot for the stock solution of carvone, which was a clear solution, the second a co spot of carvone solution and reaction mixture, which was a thick, black mixture. The third spot was designated just for the reaction mixture. The TLC plates began at the same level, then after every 15 minutes the carvone stock solution moved closer to the baseline, while the reaction...
