 OK, so let's try this one again. It says, how many of the bonds in this compound are formed by the overlap of an Sb2 molecular orbital and an Sb3 molecular orbital? So remember what we said. These things, these CH3s, are methyl groups. So if those methyl groups are scaring you, you can just expand them. So let's just quickly do that, because there was a little bit of concern before. And I say, instead of just trying to do, so that said, two methyl groups up there, instead of just trying to do what the problem says, we can figure out what all of these, the hybridization of all of these carbons are. So remember hybridization, Sb3 has to have what, four single bonds, we said, right? So help me out. Which ones are Sb3? If I point to one, say yes, or something like that. No. Yeah, so say no if I don't, too. What about L? Yeah, no. No, right? No. Yes. Yes, so that's Sb3, right? That one? Sb3. Sb3. Yes. This one? Yes. Sb3. This one? Sb3. This one? No. This one? Negative. This one? Yes. Sb3. Sb3. This one? This one? Yes. This one. Yeah, they're all Sb3. OK, so Sb2 ones are going to have what type of bonding around them? One double. One double and two singles in this case. So do we have anything that is like that? So what is this? Is this an Sb2? Yeah. What about that one? Absolutely. Yeah, and what about that one? No. No. No. Uh-uh. What are those ones? Sb's. Sb's. OK, so this one is a what, did we say? Sb2 and Sb2, right? So did we get all of them? I believe so. So it wanted us to do Sb3 and Sb2 overlap. So that's an Sb2, Sb2, right? Here's an Sb3, Sb2 overlap. So that's one. Sb2, Sb3. There's one. You guys see any more? I only see the two. So I would say the answer to this is everybody OK with that? Questions before we kill it? OK, wonderful.
