The correct combination is :
As we learned
Weak field Ligand -
These are the ligands which do not pair the electron in inner d-orbital.
- wherein
For example: etc
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
Cl- is weak field ligand CO is strong field ligand
(no pairing of electron)
