232162 The two isomers $X$ and $Y$ with the formula $\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5} \mathrm{ClBr}_{2}$ 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 due to 3 moles of particles. The structural formulae of $\mathrm{X}$ an $\mathrm{Y}$ respectively are

1 $\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{5} \mathrm{Cl}\right] \mathrm{Br}_{2} ;\left[\mathrm{Cr}\left(\mathrm{H}_{2} \mathrm{O}\right)_{4} \mathrm{Br}_{2}\right] \mathrm{Cl} \cdot \mathrm{H}_{2} \mathrm{O}$
