This is my lab procedure... please answer the following
1. Describe how the extraction is used to isolate the camphor.
2. Describe the reaction occurring and explain the catalytic cycle involving NaClO.
2. Add 1.0 g (6.5 mmol) of borneol, then 4 mL of ethyl acetate and a magnetic stir bar to the round bottom flask. 3. Stir the mixture until the solid dissolves using the stir bar. While stiring, add 0.08 g sodium chloride and 1.5 mL of distilled water to the flask 4. Add 20 ml of bleach to the separatory funnel. Make sure the stop cock is closed to start with 5. Next add the bleach solution to the reaction mixture in small portions with while stirring for a period of 10 minutes or more Monitor the temperature to control the rate of addition so that the temperature remains below 50°C. Have an ice water bath nearby to cool the reaction mixture if it begins to approach 50°C. When the addition is complete, seal the flask with Paraflim and stir for 30 minutes or more 6. Continue to stir the mixture for 50 minutes at room temperature, then add another 0.03 g sodium chloride 7. Stir for a further 10 minutes, then add 15 mL distilled water 8. Add a "spatula tip of sodium bisulfite to reduce any unreacted NaCIO, then test the aqueous layer with starch-iodide paper: a blue-black color indicates that more sodium bisulfite is needed 9. Separate the layers using a separatory funnel. Drain the lower (aqueous) layer into a 50 mL Erlenmeyer and label it as flask A this is to be extracted further. Pour out the upper layer (ethyl acetate) into another 50 mL Erlenmeyer and label as flask B; this 10. Return the aqueous layer (from flask A) to the separatory funnel and extract three more times with 5 mL of ethyl acetate. Each 11. Now return the organic layer (in flask B) to the separatory funnel and extract this organic solution with 5 mL saturated sodium 12. Dry the organic layer in flask B further by adding some crystals of using sodium sulfate. Transfer the dried solution (by will be used to hold the organic extracts time put the upper organic layer into flask B, until you end up with one big organic extract chloride solution, placing the lower layer into flask A and the upper organic layer into flask B decanting) into a pre-weighed (labeled) 50 mL beaker and let it dry in the fume hood for 30 minutes. You should be left with a final white powder product of camphor. Weigh the flask to determine the amount of crude wet product. 13. Allow your product to dry (preferable in a desiccator) overnight and reweigh it the next day. Use the weight of the dried/purified product to determine the % yield 14. Assess the purity of the final product using FTIR spectroscopy
