Question

Which would exhibit co-ordination isomerism
(a) [Cr(NH₃)₆][Co(CN)₆] (b) [Co(en)₂Cl₂]
(c) [Cr(NH₃)₆]Cl₃ (d) [Cr(en)₂Cl₂]⁺

Answer 1

(a) [Cr(NH₃)₆][Co(C N)₆]  will exhibit co-ordination isomerism

Explanation:

This type of isomerism is observed in the coordination compounds having both cation and anionic complex ions. The Ligands are interchanged in both the cation and anionic ions to form isomers.

co ordination isomer of Cr(NH₃)₆][Co(C N)₆ will be Co(NH₃)₆][Cr(C N)₆]
