- A.It exhibits linkage isomerism and is diamagnetic.
- B.It exhibits ionization isomerism and is paramagnetic.
- C.It exhibits hydrate isomerism and is diamagnetic.
- D.It exhibits coordination isomerism and is paramagnetic.
Show correct answer & step-by-step solution
Correct answer: A — It exhibits linkage isomerism and is diamagnetic.
Solution
- The ligand is an ambidentate ligand, allowing for linkage isomerism.
- The oxidation state of is , which has a configuration.
- In the presence of strong field ligands like and , the electrons pair up in the orbitals.
- The resulting configuration is , making the complex diamagnetic.
- Hence the answer is (A).
