If we chose to use dichloromethane for our extraction, which layer would be the organic layer? Why? Ethanol is miscible in water. Can it be used to extract the caffeine? Why or why not?

If the original organic solvent was dichloromethane and water was used as the aqueous extraction solvent, which layer would you expect to be at the top and why?

Questions: Based on what happened in this experiment, is caffeine more soluble in water or more soluble in dichloromethane? Explain your reasoning. Methanol is miscible with water. Assuming that caffeine is soluble in methanol, could you use methanol as a solvent to extract caffeine from tea (rather than using dichloromethane as the extraction solvent)? Explain why or why not. Go through the procedure thoroughly and list all the places where you definitely lost caffeine.
