  4. An organic compound A , C8H4O3 in dry benzene in the presence of anhydrous AlCl3 gives compound B. The compound B on treatment with PCl5, followed by reaction with 1 F/Pd/( BaSO4) gives compound C, which on reaction with hydrazine gives a cyclised compound D (Cl4H10N2).Identify A , B , C and D . Explain the formation of D from C.
