In the attachment, the oxygen with the double bond and Negative Formal charge, is that even possible? Can oxygen expand its Octet like that? I have never seen that before...
It isn't possible. An element has to be in the 3rd period or lower to expand its octet (those elements have access to d orbitals). Also notice that the carbonyl carbon has 5 bonds and is also violating the octet rule.
