Vedclass · Answer

(D) In the given compounds,the number of water molecules present in the coordination sphere and in the ionization sphere is different. Specifically,in $[Cr(H_2O)_6]Cl_3$,all $6$ water molecules are coordinated to the metal ion. In $[Cr(H_2O)_5Cl]Cl_2 \cdot H_2O$,only $5$ water molecules are coordinated,while $1$ water molecule acts as a lattice water (solvent of crystallization). This difference in the number of water molecules inside and outside the coordination sphere characterizes hydrate isomerism,which is a type of solvate isomerism.

The pair of complex compounds $[Cr(H_2O)_6]Cl_3$ and $[Cr(H_2O)_5Cl]Cl_2 \cdot H_2O$ are an example of
