The two homers X and Y with the formula Cr(H2O)5ClBr2 were taken for experiment on depression in freezing point.It was found that one mole of X gave depression corresponding to 2 moles of particles and one mole of Y gave depression due to 3 moles of particles.The structural formula of X and Y respectively are
(A)[Cr(H2O)5Cl]Br2 ,[Cr(H2O)4Br2]Cl.H2O
(B)[Cr(H2O)5Cl]Br2,[Cr(H2O)3ClBr2.2H2O
(C)[Cr(H2O)5Br]BrCl ,[Cr(H2O)4ClBr]Br2.H2O
(D)[Cr(H2O)5Cl]Br2,[Cr(H2O)4Cl2]Br.H2O
(E)[Cr(H2O)4Br2]Cl.H2O ,[Cr(H2O)5Cl]Br2
