Many important drugs contain the amine functional group, which makes them basic. Many drugs also contain an amide group, which is effectively neutral. Suggest a way to separate ephedrine, a stimulant and decongestant drug shown below, from phenacetinGive your answer in the form of a flow chart in which a hypothetical mixture of phenacetin and ephedrine are separated by extraction. suggest an organic solvent that would be appropriate to the separation. Show any relevant chemical reactions and structures at each point in your chart. Consider in your answer that both compounds contain nitrogen atoms. Explain how they will nonetheless differ in reactivity and solubility
