What kind of isomerism exists between $[C r (H_{2} O)_{6}] C l_{3} (v i o l e t)$ and $[C r (H_{2} O)_{5} C l] C l_{2} . H_{2} O (g r e y i s h - g r e e n)$ ?

(b) Solvate isomerism
(c) Ionisation isomerism
(d) Coordination isomerism

Solution

Answer: (b). Solvate isomerism

Solute isomerism to shown when two compounds having the same molecular formula differ by whether it has solvent molecule is directly bonded to a metal ion or is present as free solvent molecules in the crystal lattice.
When water is present as a solvent and shows this type of isomerism then it is known as hydrate isomerism or Solvate isomerism.
Coordination compound $[C r (H_{2} O)_{6}] C l_{3}$ and $[C r (H_{2} O)_{5} C l] H_{2} O . C l_{2}$ are solvate isomers, because water is exchanged by chloride ion. This is why both of them show different colour on exposure to sunlight.
