The two isomers X and Y with the formula `Cr(H_(2)O)_(5)ClBr` 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 to 3 moles of particles. The structural formulae of X and Y raspectively areA. `[Cr(H_(2)O)_(5)Cl]Br_(2), [Cr(H_(2)O)_(2)Br_(2)]Cl.H_(2)O`B. `[Cr(H_(2)O)_(5)Cl]Br_(2), [Cr(H_(2)O)_(3)ClBr]H_(2)O`C. `[Cr(H_(2)O)_(5)Br]BrCl, [Cr(H_(2)O)_(4)ClBr]H_(2)O`D. `[Cr(H_(2)O)_(4)Br_(2)]Cl.H_(2)O, [Cr(H_(2)O)_(5)Cl]Br_(2)`

1.	The two isomers X and Y with the formula `Cr(H_(2)O)_(5)ClBr` 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 to 3 moles of particles. The structural formulae of X and Y raspectively areA. `[Cr(H_(2)O)_(5)Cl]Br_(2), [Cr(H_(2)O)_(2)Br_(2)]Cl.H_(2)O`B. `[Cr(H_(2)O)_(5)Cl]Br_(2), [Cr(H_(2)O)_(3)ClBr]H_(2)O`C. `[Cr(H_(2)O)_(5)Br]BrCl, [Cr(H_(2)O)_(4)ClBr]H_(2)O`D. `[Cr(H_(2)O)_(4)Br_(2)]Cl.H_(2)O, [Cr(H_(2)O)_(5)Cl]Br_(2)`
Answer» 1 mole of complex X giving 2 moles of particles will be `[Cr(H_(2)O)_(4)Br_(2)]Cl.H_(2)O` i.e. `\|Cr(H_(2)O)_(4)Br_(2)]^(+)+Cl^(-)` 1 mole of complex Y giving 3 moles of particles will be `\|Cr(H_(2)O)_(5)Cl\|Br_(2)` i.e. `\|Cr(H_(2)O)_(5)Cl^(-)\|^(2-)+2Br^(-)`.
