Biradical vs Lone Pair

[Jessica Beroukhim 3K]

What's the difference between a biradical and a molecule where one atom has a lone pair on it?

[Jason Liu 1C]

Biradicals have two unpaired electrons, meaning each electron is in a different orbital. An atom with a lone pair has two electrons in the same orbital.

[Ivy Lu 1C]

A biradical is a molecule with two unpaired electrons and a lone pair is when two valence electrons that aren't part of bonding for an atom. For a biradical, the two unpaired electrons on usually on different atoms.

Lone pair refers to valence e- that aren't shared with another atom. Biradical refers two unpaired electrons
