Using A flow diagram, show the separation of a mixture containing p-bromoacetanilide, N-cyclopentyl-N-methyl-N-propylamine (N means the group is attached to the nitrogen of the amine) and m-nitrophenol. Specify the organic solvent and aqueous solutions to be used for the separation. Provide the exact acid-base reaction that occurs during each step of the separation.
