This is the answer I selected which is incorrect. Thank you
You are trying to separate a mixture of benzoic acid (BA) and benzene (BZ) by liquid-liquid extraction. Your two solvents are 1.0 M NaOH and diethyl ether. If you add your mixture to the two solvents in a separatory funnel, which layer would each compound migrate toward? Both compounds will be in the organic layer since they are both largely nonpolar. Both compounds will be in the aqueous layer since the BA will have ion-dipole interactions with water and the BZ will be attracted to the nonpolar ring of BA. Both compounds will be in the organic layer since BZ is nonpolar, and BA is only soluble in water at low pH. BA would migrate to the aqueous layer due to ion-dipole interactions, and BZ would migrate to the organic layer due to London dispersion forces.
