    This question usually asks why biphenyl is formed?

    Benzene is formed when the reaction is quenched as the reaction is usually carried out with excess Grignard Reagent.

    PhMgBr + H2O -> PhH + Mg2+ + HO- +Br-

    The inorganics form a whitish sludge initially and then the reaction is usually acidified to get the magnesium salts into solution.
