Hi Danielle – You can think of the situation where both carbons have free radicals as a “resonance form” of a pi bond.
(my answer here could, and should, go a lot deeper, but I’m just going to keep it simple in this case).

Cyclic or acyclic?

I’m confused as to where to locate the Pi bonds when looking at the MO orbital. Since the two valence orbitals in cyclobutadiene are in non bonding orbitals and are singly occupied, why then do we see two pi bonds? I understand how Pi 1 represents a double bond but I don’t see where the second bond is. Thank you!
