The first reaction is a Grignard reaction where phenylmagnesium bromide (PhMgBr) adds to the carbonyl group of benzophenone to form a complex. In the second step, the complex is treated with an acidic work-up which hydrolyzes the ether and protonates the alcohol. The major product of this reaction sequence is III, which is the hydroxylated form of benzhydrol. The other products (I, II, IV, and V) are minor products that could form during the reaction but are not expected to be major products.
