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! :)

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
