Two isomers X and Y with the formula Cr(H_2O)_5ClBr_2 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 corresponding to 3 moles of particles. The structural formulae of X and Y respectively are |

Answer» `[Cr(H_2O)_5Cl]Br_2 , [Cr(H_2O)_4Br_2 ] ClH_2O` `X=[Cr(H_2O)_4Br_2]Cl.H_2O hArr [Cr(H_2O)_4Br_2]^(+) Cl^(-)` Y gave depression corresponding to 3 moles of particles. `Y=[Cr(H_2O)_5Cl]Br_2 rArr [Cr(H_2O)_5Cl]^(2+) + 2Br^(-)` |
