What is the consequence of π-bonding on the Δo values in octahedral complexes?
Understand the Problem
The question is asking about the effects of π-bonding on the Δo values in octahedral complexes, specifically how such bonding influences the energy difference between the sets of d-orbitals in these complexes.
Answer
π-backbonding increases Δo; π-donation decreases Δo.
The consequence of π-bonding on Δo values in octahedral complexes is that π-backbonding increases Δo by destabilizing d-orbitals, while π-donation stabilizes d-orbitals and decreases Δo.
Answer for screen readers
The consequence of π-bonding on Δo values in octahedral complexes is that π-backbonding increases Δo by destabilizing d-orbitals, while π-donation stabilizes d-orbitals and decreases Δo.
More Information
π-bonding in octahedral complexes influences the crystal field splitting parameter Δo, altering the energy levels of d-orbitals according to the nature of the ligand.
Tips
Be mindful of whether the ligand acts as a π-donor or π-acceptor when predicting the change in Δo.
