Well, what has diphenylmethanol got that benzophenone ain't got?

Explanation:

The answer is of course an hydroxyl substituent, a strongly POLAR functional group; i.e. #(H_5C_6)_2CH(OH)# versus #O=C(C_6H_5)_2#. And to test the polarity we might assess the solubility of each compound in weakly polar solvents, such as diethyl ether, and in a strongly polar solvent such as ethanol....
