Radicals and Biradicals in VSEPR Model

[Benjamin Chen 1H]

Would we consider the single, unpaired electrons on radicals and biradicals each a single region of electron density?

[Melody Wu 2L]

Yes, I believe they do count as a region of electron density when determining hybridization. Those single electrons still occupy an orbital, although the effects on the shape may be different since it's a single electron instead of two.

[Ria Nawathe 1C]

I agree with the previous answer, Dr. Lavelle mentioned in one of his lectures that the unpaired electron in radicals like NO2 is considered a region of electron density.

[Kristina Krivenko 3I]

Yes, Dr. Lavelle mentioned in one of the lectures that single electrons are also counted as a single region of electron density, along with lone pairs of electrons & bonding pairs.

[Eileen Quach Dis 2A]

Yes,we would consider them as single regions of electron density.
