InterviewSolution

1.	Why is [NiCl4]2- paramagnetic while [Ni(CN)4]2- is diamagnetic? (Atomic number of Ni = 28)
Answer» In [NiCl₄]^2-, due to the presence of Cl^-a weak field ligand no pairing occurs whereas in [Ni(CN)₄]^2-, CN^-is a strong field ligand and pairing takes place/diagrammatic represenlation.
