How do I determine paramagnetic species in homonuclear diatomic molecules?

It is determined by looking at the molecular orbital diagrams. A blowby version is:

![Inorganic Chemistry, Miessler et http://al.](https://useruploads.socratic.org/3QhwAeTySzKZMtP7x3se_ORBITALS_-_OrbitalMixing2ndperiod.png)

From these, which one has the unpaired electron(s)? That one is paramagnetic. Did you determine it to be "B"_2? If so, what molecular orbitals are holding these unpaired electrons?
