The determining factor for the given layer that the solute prefers is intermolecular forces of attraction between the solute and the given layer (aqueous layer and organic layer).
In general, polar solute prefers to interact with polar solvent layers such as water, alcohol etc
Non-polar solute prefers to interact with non-polar solvent layers such as benzene. cyclohexane, carbon tetrachloride etc
