1. Consider three aqueous solutions of 0.100 mM benzene, chlorobenzene and 1,4 dichlorobenzene ($\log K_{ow}$ values of 2.13, 2.84, and 3.44, respectively). Calculate the concentrations for each compound (in aqueous and octanol phases) if 200 mLs of each solution is extracted with 10.0 mLs of octanol. Given that Cl is highly electronegative, why is the most chlorinated compound the most strongly extracted?
