Re: MO Theory [ENDORSED]
A molecule is paramagnetic if there are unpaired electrons in looking at an MO diagram. For example, B2 has two electrons in both the bonding and anti-bonding sigma s bonds, and one in both pi px and pi py. Because pi px and pi py have just one, they are unpaired and therefore paramagnetic. A molecu...
