Question

Which would exhibit coordination isomerism?

Options

• [Pt(NH₃)₄] [CuCl₄]

• [Co(H₂O)₆]Cl₃

• [Co(NH₃)₆]Cl₃

• [Cr(en)₂Cl₂]Cl

Answer 1

[Pt(NH₃)₄] [CuCl₄]

Explanation:

In coordination compounds with both cationic and anionic complex ions, coordination isomerism is seen. Isomers are formed when the ligands in cationic and anionic ions are swapped.
