So there's the structure of carbon monoxide. Let's figure out the formal charge of the 2S. Okay, so formal charge, call me out. It's the very good. Okay, you can never do electrons minus. One half, it's up there guys. Bonding electron. Minus the non-bonding electron. Okay, so how many day ones electrons does carbon normally have? Come on, you guys. Bonding electrons, in this case, two, four, six. Right? And non-bonding electrons. So four minus three minus two. Right? So what's the formal charge on carbon? Okay, good. So since carbon monoxide is uncharged, what would you expect the charge to be on oxygen, formal? Plus one. Let's just make sure there's some case. So formal charge equals what? Good job guys. That's number of valence electrons minus one half the bonding electron minus the non-bonding electron. So oxygen normally has how many polar trots? Minus three. Six. Six. Minus two. So is that the case? Six minus three minus two. Six minus five. Everybody okay with it? So again, I think you have to be given the structure to be able to do. If not, you're finding it during the point in time when you're building the show. Any questions on this type of problem?
