Question:
The ionisation isomer of $[Cr(H_2O )_4Cl(NO_2 )]Cl$ is
The ionisation isomer of $[Cr(H_2O )_4Cl(NO_2 )]Cl$ is
Updated On: Jun 14, 2022
- $[Cr(H_2O )_4 (O_2N)]Cl_2$
- $[Cr(H_2O )_4 Cl_2 ](NO_2)$
- $[Cr(H_2O)_4Cl(ONO)]Cl$
- $[Cr(H_2O )_4Cl_2(NO_2 )]. H_2O$
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Ionisation isomers are the complexes that produces different ions in solution, i.e. they have ions interchanged inside and outside the coordination sphere. $[Cr(H_2O)_4Cl(NO_2)]Cl$ and $[Cr(H_2O)_4Cl_2](NO_2)$ have different ions inside and outside the coordinate sphere and they are isomers.
Therefore, they are ionisation isomers.
Therefore, they are ionisation isomers.

Concepts Used:
Coordination Compounds
A coordination compound holds a central metal atom or ion surrounded by various oppositely charged ions or neutral molecules. These molecules or ions are re-bonded to the metal atom or ion by a coordinate bond.
Coordination entity:
A coordination entity composes of a central metal atom or ion bonded to a fixed number of ions or molecules.
Ligands:
A molecule, ion, or group which is bonded to the metal atom or ion in a complex or coordination compound by a coordinate bond is commonly called a ligand. It may be either neutral, positively, or negatively charged.
