What type of isomerism is exhibited by $\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_3$ and $\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_5 \mathrm{Cl}\right] \mathrm{Cl}_2 \cdot \mathrm{H}_2 \mathrm{O}$
Coordinate
Solvate
Ionization
Linkage
Solution
$\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_3 \text { and }\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_5 \mathrm{Cl}^{-}\right] \mathrm{Cl}_{2:} \mathrm{H}_2 \mathrm{O}$
(I) In compound I, the solvent water is directly bonded to Cr .
In compound II, $\mathrm{H}_2 \mathrm{O}$ appears as the free solvent molecule.
$\therefore \quad$ I and II represent solvate isomers.
