Solution
Correct Answer:
Coordination isomerism
Coordination Isomerism occurs in salts where both the cation and anion are coordination complexes.
- It arises from the interchange of ligands between the cationic and anionic metal centers.
- In the first salt, NH3 is with Co and CN is with Cr.
- In its isomer, NH3 is with Cr and CN is with Co.
- They share the same empirical formula but have different identities of the complex ions.
This medium difficulty chemistry question is from the chapter coordination compounds, covering the topic of coordination isomerism. It appeared in the 2025 exam.
