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.
