Patricia Mora Chem 3BL 03/03/10 Dehydrogenation and Hydrogenation In this experiment, we examined the reaction of monoterpene carvone with Pd/C and heat. In addition, we attempted to isolate the product of carvone and Pd/C by using acids and bases and by separating aqueous and organic layers. The purpose of this experiment was to determine the relative stability of isomeric alkenes through hydrogenation of alkenes with hydrogen gas and metal catalyst or transfer hydrogenation. During the transfer-hydrogenation reaction, Pd/C was dehydrogenated and donates hydrogen to carvone, resulting in the cyclohexane part of carvone becoming a benzene ring in the presence of heat. Gaining more hydrogens to create double bonds made the product more stable, and also aromatic. When the bonds are broken, energy is added to the reaction while forming bonds releases energy from the reaction. Two C-H bonds were broken (412 kJ/mol + 412 kJ/mol = +824 kJ/mol is added), A C=C double was broken (824 kJ/mol + 614 kJ/mol = +1438 kJ/mol added to

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
