mechanism and explanation please

Mix cyclohexylmagnesium chloride and benzaldehyde (Grignard Addition folder) together in Et2O as the solvent and allow the reaction to stir until it is complete. Choose which of the following possibilities match your observations from the experiment. Select all that apply. The product was a salt that would need to be quenched with an acid The reaction is very slow and does not consume all starting materials The reaction mixture would be at highly basic pH The reaction is quite fast with both starting materials being consumed quickly The reaction mixture would be at essentially neutral pH The addition of the Grignard reagent was probably reversible
