Results In this experiment, we started with 0.404 grams of Olive Oil and ended with 0.312. Our theoretical yield was 0.407, leading to a percent yield of 76.7%. Our percent yield was adequate, knowing that a 100% yield is nearly impossible. The melting point of our product was 38ºC - 40ºC. We expected our melting point to be slightly higher (possibly 10 degrees higher). This low melting point could have been caused by impurities such as excess palladium catalyst or even particles from the boiling chips added to the mixture. Conclusions Our reaction was successful, our percent yield was above 50 percent, our product solidified in the ice bath, and our melting point was in the desired range.

Unformatted text preview: Questions 1. Saturating Olive Oil causes solidification. Therefore, we can test if our reaction was successful by cooling the olive oil below room temperature and see if it solidifies. If it does, our reaction was successful. 2. Ammonium formate (HCOO- NH4+) can also be used as a hydrogen source in a transfer hydrogenation, giving up one equivalent of hydrogen. Write a balanced equation showing the hydrogenation of 1-butene with ammonium formate in the presence of a Pd/C catalyst. • NH 4 CO 2 H/(Pd/C) NH 3 (g) + CO 2 (g) + H 2 (g) so CH 3 CH 2 CH=CH 2 (g) + NHCO 2 H/(Pd/C) NH 3 (g) + CO 2 (g) + CH 3 CH 2 CH 2 CH 3 (g)...

    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.
