Question

What is the hydrate isomerism? Explain with in example?

Answer 1

Solvate isomers or hydrate isomerism are the isomers which have the same composition but differ with reference to the number of solvent ligand molecules as well as the counter ion in the crystal lattice.

For example $\left[Cr\right(H_{2}O{)}_6]C{l}_3$ is violet colored, $\left[CrCl\right(H_{2}O{)}_5]C{l}_2{H}_{2}O$ is blue-green, and $\left[CrC{l}_2\right(H_{2}O{)}_4]C{l}_2{H}_{2}O$ is dark green.
