Orbital Hybridization and Quantum Numbers

Postby Ben Chen » Mon Oct 12, 2020 6:07 pm

When an atom, say Carbon, hybridizes to sp3, sp2, or sp, does the original set of quantum numbers for an noncovalently bonded C atom still apply to the hybridized Carbon? Or, do we use a different method to depict/describe the electrons in hybridized orbitals of a certain atom in a molecule?

Hi,

Here is a really nice summary of hybridization on Khan Academy. To answer your question, you would depict the electrons differently. In the case of sp3 hybridization for carbon, you would promote the 2s orbital of the carbon to an sp3 orbital, and "demote" the 3 2p orbitals to an sp3 orbital. I'm using "promote" and "demote" to describe their respective energies. 1:30 in the video is a good depiction of what I'm trying to say.

so on atomic spectras do the dark lines represent different orbitals or different energy levels?

The dark lines on an absorption spectra represent the wavelengths that are absorbed by an element.
