5. (8 pts) Oxidation of Benzyl Alcohol (Experiment 9) Z.equiv Nis (a) In this reaction, why is an UV lamp used? Circle your answer. (i) To monitor the progress of the reaction in terms of color change of the reaction (ii) To provide a catalyst for protonation of the aicohol (iii) To provide enough energy to generate radicals to initiate the radical reaction (iv) To neutralize the iodine present in solution (b) At the end of the NIS reaction (oxidation of benzyl alcohol), you added aqueous sodium thiosulfate to the reaction during the workup. What was the purpose of this step? Circle your answer. (i) To reduce molecular iodine to iodide. (ii) To remove the solvent from the reaction (iii) To dry the organic layer (iv) To dissolve the product that had formed (c) What is the other potential oxidation product that you had to consider when you performed this experiment? Draw it. (d) Analysis of crude reaction mixture by gas chromatography. Use of non-polar column. Standards identity, area and retention time are in the given table. (i) Ienoring contributions from solvent, determine the \% composition of the major reaction species. Show your work. (ii) What does this information in the GC tell you about the outcome of your reaction? Be specific, as you would in your lab report discussion/conclusions write-up
