(C) Hydrate isomerism occurs when water molecules can be either directly coordinated to the metal ion or present as free water of crystallization.Example: $CoCl_3 \cdot 6H_2O$ can exist as:$(1)$ $[Co(H_2O)_6]Cl_3$$(2)$ $[Co(H_2O)_5Cl]Cl_2 \cdot H_2O$$(3)$ $[Co(H_2O)_4Cl_2]Cl \cdot 2H_2O$In these isomers,the number of water molecules acting as ligands and the number of water molecules of hydration both change.
