10.

All of these structure formulas are correct, except for ___?

11.

This is the Lewis Dot Structure for Carbon Monoxide, a colorless, odorless, and poisonous gas. This structure does not fit the HONC 1234 Rule at all, but does fit the Octet Rule. What is going on here?

The Octet Rule and the HONC 1234 Rule are just rules of thumb. They don't explain the structures of all molecules. Chemists have devised other means for predicting and explaining this structure.

I plan to take AP Chemistry to find out what is going on here.

The body can't easily break the triple covalent bond of carbon monoxide. So when you breath it in it displaces the oxygen (O₂) in your lungs. CO is an asphyxiant.
