Scott Coon Experiment 7 Organic – 201 I.)Introduction: Due to great work of analyzing Northern Pines Chemical Company’s column- packing material, our crack team of highly specialized scientists have been hired to analyze other random chemicals. Northern Pines needs to find another technique for oxidizing Isoborneol to produce sought after camphor as a product. Previous techniques for oxidation of Isoborneol involved a highly toxic chromic acid. The solution and also the task at hand is to carry out the oxidation of Isoborneol with laundry bleach to find out if the reaction does in fact produce any camphor. II.)Table of Reagents: This table shows all the reagents for the experiment and their associated values Compounds M.W. (g/mol) m.p. °C b.p. °C d (g/mL) amt.

Unformatted text preview: 1.)Under the hood combine .39g (2.5mmol) of Isoborneol with 0.20mL of glacial acetic acid 2.) Drop in a stir bar 3.) Measure 5.0 mL of 5.25% sodium hypochlorite solution (Clorox or bleach) and keep the vial capped 4.) While stirring, use a pipet to measure 4.5 mL of NaOCl into the solution at the rate of 1 mL per second 5.) After NaOCl has been added, seal the flask with Parafilm and stir the reactants for 30 minutes at room temperature 6.) Test reaction for excess hypochlorate by transferring drops of solution onto a starch-iodide strip every five minutes after the first ten minutes **If test shows negative (unreactive) add enough sodium hypochlorite to make it positive 7.) When reaction period is over, test the solution and add enough sodium bisulfate to make it negative Separation 8.) Cool the reaction mixture to 5 C or below and collect product by vacuum filtration 9.)Dry at room temperature and weigh/record the mass...
