Molecular orbital theory of heterodiatomics?

Click For Summary
SUMMARY

The order of molecular orbitals (MOs) in heterodiatomics is influenced by the differing electronegativities of the constituent atoms. In the case of nitric oxide (NO), the molecular orbital configuration is represented as 1σ, 2σ, 1π, 3σ, where σ denotes bonding orbitals and π denotes non-bonding orbitals. The distinction between configurations such as 1σ, 1σ* (antibonding) versus 1σ, 2σ arises from the specific interactions in heterodiatomic molecules compared to homodiatomics. Understanding these differences is crucial for accurately predicting molecular behavior in heteronuclear diatomic molecules.

Homework Statement


What determines the order of the Molecular orbitals in heterodiatomics?

The Attempt at a Solution


In my book, I have NO with an order of

1s 2s 3s 1p 2p 4s

Where s means sigma and p means pi.

Also sometimes I see in the book the ordering being 1sigma, 1sigma*(antibonding) instead of 1sigma, 2 sigma like in NO. Is this difference caused by homodiatomics versus heterodiatomics?

I know the order of homodiatomic MO but I don't know how to find it for heterodiatomics. Can someone clarify this? Maybe its a convention or something.
