Hello there, I did an extraction of caffeine organic lab experiment. Why is ethyl acetate used for extracting caffeine and not other solvents? I know that ethyl acetate, caffeine, and water are polar but why are two layers formed after mixing caffeine in water and ethyl acetate? I'm a little confused. I thought that polar mixes with polar and nonpolar mixes with nonpolar. Is caffeine not polar? Is ethyl acetate soluble in water? Please explain. Thank you very much! :)

Why would it be unwise to use 100% ethyl acetate as the first mobile phase you test when determining the best mobile phase to separate the mixture of analgesics in Procedure? Why do polar compounds move slower up the silica TLC plates than nonpolar compounds? Why does increasing the polarity of the mobile phase increase the rate at which all compounds move up the plate?
