its) Product Information: Mass of Hydrogenated Olive Oil: 1.689 Percent Yield of Hydrogenated Olive Oil:_117.04% (show calculations) d.689 x 100% =497.04€ 0.5389 pints) Product Your product will be handed in to your TA in a vial with the following informat hydrogenated olive oil, the weight of the vial + the cap, and the weight of you product will be graded on both yield and purity. moints) Laboratory Technique Points for good lab technique. You are not required to complete anything he give your score on the rubric. points) Experimental Write an experimental section for the hydrogenation of olive oil. This should double spaced. There is very specific formatting for this section, so please documents on myCourses on how to write a proper experimental section. In section should include only detail relevant to complete the experiment and Remember to include all analytical data, like mass, MP, yield, and IR. -oints) IR Spectra Attach the IR spectra you obtained in lab (both of olive oil and hydrogenated relevant peaks labeled with their bond assignments.

Answer 1

Answer to question 1:

The hydrogenation is performed by catalytic transfer hydrogenation process (CTH). Here, an organic molecule such as cyclohexene is used as a source of hydrogen. Pd metal is used as a catalyst which transfers hydrogen from cyclohexene to the olive oil. The cyclohexene is converted to benzene in this process. After the completion of hydrogenation, the Pd metal remains in soluble in the reaction flask. Therefore, the solution is filtered over celite to remove the insoluble Pd metal.

Answer to question 2:

As stated above, the cyclohexene is used as a source of hydrogen. Therefore, cyclohexene was added to the reaction medium.

Answer to question 3:

The most significant changes found on comparing these two IR spectra are as following:

The alkene C-H stretching band at 3004 cm^-1 is present in the spectrum in olive oil, whereas it is absent in the spectrum of the hydrogenated product. Therefore, the spectra comparison strongly indicates that the olive oil is hydrogenated.
