Q42.Low oxidation state of metals in their complexes are common when ligands (1) have good π -accepting character (2) have good σ -donor character (3) are havind good π -donating ability (4) are havind poor σ -donating ability
What This Question Tests
This question assesses the understanding of how ligand properties, particularly pi-accepting character, stabilize low oxidation states of metals through synergic bonding in coordination complexes.
