Co Ordination Compounds Question 79

Question: Coordination isomerism is caused by the interchange of ligands between the

[UPSEAT 2002]

Options:

A) Cis and Trans structure

B) Complex cation and complex anion

C) Inner sphere and outer sphere

D) Low oxidation and higher oxidation states

Show Answer

Answer:

Correct Answer: B

Solution:

Coordination isomerism is a type of isomerism in coordination compounds where the distribution of ligands between the complex cation and complex anion is different, while the overall composition remains the same.

Key points:

  1. This type of isomerism occurs in compounds containing both a complex cation and a complex anion.

  2. The ligands are exchanged between the cation and anion, resulting in different structures with the same overall formula.

  3. The oxidation states of the metal ions and the total number of each type of ligand remain constant.
