1. Using a burette, measure the cyclohexene (6.0 mmol) and transfer to a 125 mL erlenmeyer, along with acetone ([Cyclohexene] = 1 M). Add a stirbar. 2. Cool the solution in an ice-bath for 10 minutes with magnetic stirring. 3. Meanwhile, in a 2nd 125 mL erlenmeyer, dissolve Oxone (15.6 mmol) in deionized water ([Oxone] = 0.60 M). 4. Attach a ring-clamp right over your flask. Add a closed separatory funnel, such that the bottom tip is partially inserted in the flask. 5. Add your Oxone solution into the separatory funnel. 6. When your cyclohexene solution is sufficiently cold, gently open the bottom valve of the separatory funnel to add the Oxone solution. Adjust the valve to obtain a flow of approximately 1–2 drops/second. 7. Once the addition is complete, rinse the separatory funnel with a few millilitres of water. 8. Remove the flask from the ice bath, and allow the reaction to stir at room temperature for 20 minutes. 9. After 20 minutes, add 12.5 M HCI (14.9 mmol) dropwise to the stirring solution. Allow the reaction to stir for 10 minutes before proceeding with liquid-liquid extraction (p.8). c) Assume that a drop of 12.5 M HCI is approximately 50 µL (or 0.05 mL). How many drops of concentrated acid should you add at the end of the reaction?
