Question

The hydrate isomer of $\left[Cr\right(H_{2}O{)}_{5}Cl]C{l}_2.H_{2}O$ is/are

• A. $\left[Cr\right(H_{2}O{)}_{4}C{l}_2]Cl.2H_{2}O$
• B. $\left[Cr\right(H_{2}O{)}_{3}C{l}_3]3H_{2}O$
• C. All of the above.
• D. $\left[Cr\right(H_{2}O{)}_6]C{l}_3$

Answer 1

The correct option is C All of the above.

When water molecules are exchanged between coordination sphere and ionisation sphere, the resulting isomers are called hydrate isomers. This phenomenonon is hydrate isomerism.

Here, the water molecule and the $C{l}^{-}$ ligands are exchanged.
Hence, all are the hydrate isomers of given complex compound.
