Of the following complex ions, which is diamagnetic in nature?
As we learnt in
Strong Field Ligand -
These are the ligands which pair the electron in inner d-orbital and makes required d-orbitals empty/available.
- wherein
For example: CO, CN etc
Electronic configuration of Ni2+ : 3d8 4s°
Since CN- is a strong field ligand, the d electrons will pair up and leave one d orbital vacant for dsp2 hybridization
find e - config
Since, there are no unpaired e-s in [Ni (CN)4]2-
So, it is diamagnetic.
