Answer 2

Answer:

The correct option is (a).

Out of the following the one that is an example of hydrate isomerism is (a) $[Cr(H_2O).]Cl_3$ and $[Cr(H_2O)Cl]Cl_2.H_2O$

Explanation:

• The isomers known as "solvate" or "hydrate" are identical in composition but differ in terms of the quantity of solvent ligand molecules present as well as the counter ion in the crystal lattice.
• Although they have the same composition and are also known as solvent isomers, they have different numbers of water molecules. Ion is directly linked to the centre metal in this case, but the rest is not.
• They are referred to as "hydrated" because the word "hydrated" is used to describe water.
• One of them is directly bonded to the essential metal, but the other is not. This is where they diverge.
• The substitution of a solvent molecule for a coordinated group results in an isomerism that is quite similar to that (Solvate Isomerism).
• Ionization isomers are coordination compounds in which the ligands in the inner and outer coordination spheres have been switched.
• The isomerism is known as hydrate isomerism in the unique circumstance when one of these ligands is a water molecule.
• One of them is different from the other in that it is directly bonded to the centre metal. 

• Examples include : the colours violet $[Cr(H_2O)_6]Cl_3$, blue-green$[CrCl(H_2O)_5]Cl_2.H_2O$, and dark green $[CrCl_2(H_2O)_4]Cl_2.H_2O$.
