Why is [NiCl 4 ] 2– paramagnetic but [Ni(CO) 4 ] is diamagnetic though both are tetrahedral?

Options

  1. AThe presence of Nickel results in stronger ligand-metal bonding, causing diamagnetism in [Ni(CO) 4 ].
  2. BThe nature of the ligands in [NiCl 4 ] 2– is different from [Ni(CO) 4 ], leading to distinct magnetic properti
  3. C[Ni(CO) 4 ] is paramagnetic due to the presence of a strong ligand like CO, while [NiCl 4 ] 2– is diamagnetic.
  4. DThe oxidation state of Ni in [Ni(CO) 4 ] is different from [NiCl 4 ] 2– , affecting their magnetic behaviour.

Correct answer

B. The nature of the ligands in [NiCl 4 ] 2– is different from [Ni(CO) 4 ], leading to distinct magnetic properti

Step-by-step solution

Correct Option is : (B) The nature of the ligands in [NiCl 4 ] 2– is different from [Ni(CO) 4 ], leading to distinct magnetic properties.
