The compounds [Cr(H2O)6]Cl3, [Cr(H2O)5Cl]Cl2.H2O and [Cr(H2O)4Cl2]Cl.2H2O exhibits : — Coordination Compounds Chemistry Question

💡 Solution & Explanation

Step 1: Identify that the given compounds have the same overall molecular formula but differ in the number of water molecules present inside and outside the coordination sphere. Step 2: Hydrate isomerism (a form of solvate isomerism) occurs when the water of crystallization is exchanged with ligand anions in the coordination sphere. Step 3: Therefore, these compounds are hydrate isomers of each other, making option (d) the correct answer.
