CHEM246 Fundamentals of Organic Chemistry Laboratory Post-lab Questions: 1 Calculate the percent recovery of eugenol from cloves (use your recovered mass of eugenol and your original mass of cloves). See Appendix II for an explanation of percent recovery calculations. mass of Eugenol = 0.10g Actual mass of cloves = 4,03.g 2 Why is saturated sodium chloride solution often used to wash the organic layer? 3 What is the difference between "drying the organic layer with sodium sulfate" and "evaporating the organic solvent?" (Hint: do these imply the same physical/chemical process? How are they the same or different?) 4 Name another organic compound that could be isolated by steam distillation. Page 12 of 13
