Question

Please can someone help me to interpret this. This was from Orgo II Williamson ether Lab. These are the results and I need help interpreting what this is showing. More especially for the discussion and conclusion section. Thank You!

(if needed here are the procedures)

1. Add a magnetic stir bar to a 25ml round or pear-shaped flask.
2. Add guaiacol (0.55ml,5mmoles) to the flask along with 3ml of 95% ethanol. Make sure the guaiacol dissolves in the ethanol before proceeding.
3. Add 1ml of 6M NaOH with stirring.
4. Attach a condenser.
5. Reflux for 10mins using a water bath. This will result in generation of a phenoxide ion.
6. Using a pipet, add 1ml of a 50% solution of (+/-)-3-chloro-1,2-propane-diolin ethanol dropwise through the top of the condenser, gradually over a period of 5-10minutes.
7. A white precipitate should form.
8. Reflux for 1 hour.
9. Remove from heat and allow to cool.
10. Remove the ethanol using a rotary evaporator.
11. Add 3ml of water to dissolve the NaCl formed.
12. Pour mixture into a separatory funnel and extract twice with ethyl acetate. (2x10ml). Wash out your 25ml round or pear bottomed flask with acetone and leave to dry. You may need it again for step 15.
13. Dry the layers with anhydrous magnesium sulfate.
14. Filter. Rinse the filtrate into a pre-weighed round or pear shaped round bottom flask. The flask should not be more than half full before going on the rotary evaporator. You may need to use a 50ml round bottom flask.
15. Remove the ethyl acetate using a rotary evaporator.
16. Cool the flask in ice water and add a magnetic stir bar.
17. Add hexanes (10ml) with rapid stirring.
18. If guaifenesin precipitates filter it off.
19. If it does not precipitate remove the solvent on a rotary evaporator.
