Hint: n this question we have used the concept of isomerism in coordinate compounds. Coordination isomerism, which can be thought of as an exchange of certain ligands from the cation to the anion, happens in compounds that have complex cationic and anionic components. As a result, two complicated chemicals that have opposite charges - one negative and the other positive are linked together.
Complete answer:Linkage isomers are two or more coordination compounds in which at least one of the ligands has a different donor atom from the others (i.e., the connectivity between atoms is different). Only a molecule with a ligand that can form two (or more) distinct bonds with the metal atom can exhibit this kind of isomerism. The list below includes various ligands that can create linkage isomers.
Ionization isomerism is the term used to describe the property of compounds that, despite having the same composition, produce distinct ions in a solution.
The exchange of one or more ligands between the cationic complex ion and the anionic complex ion is known as coordination isomerism, and it happens in compounds that have complex anionic and cationic components.
The isomers known as "solvate isomers" or "hydrate isomerism" are identical chemically but differ in terms of the number of solvent ligand molecules present as well as the counter ion in the crystal lattice.
In both [Cr(H2O)6Cl3] and [Cr(H2O)5Cl]Cl2H2O, the number of water molecules present in the coordination sphere and in the ionization sphere is different. Therefore, they exhibit hydrate isomerism.
The correct answer is D
Note: [Cr(H2O)6Cl3] is violet in colour and [Cr(H2O)5Cl]Cl2H2O is blue-green. Because water is used as a solvent, this type of isomerism is referred to as "hydrate isomerism". The quantity of solvent molecules directly bound to the metal ion distinguishes the compounds in this type of ionization isomerism. They can function in the lattice both as free molecules and as ligands.
