 Let's try to build this structure then, and I want you guys to help me. So you guys write it down. So what is this going to look like? Do you drill through things though? It's going to be linear, right? Why? Because the carbons have to be bonded to each other, right? The hydrogens have to be on the outside. So there's the hydrogen carbons. So don't just blur something out. If you don't know, build it, okay? So let's build it. How many bonds are the carbons going to have between them? Two. I think? No. Three, right? Three. Okay, so let's do that. Okay, with that. This molecule that we're building is called the settling. If you've ever used a welding torch, this stuff. So how many electron groups do you have around this carbon atom? Electron groups. Why? We talked extensively about this last time. So all of your confused looks. Why are they only two? This just counts as one. Just like a double bond, triple bond counts as one. So how many electron groups do we have around this carbon? Everybody tell me. Two, right? So what's the bond angle between those two bonds? Everybody tell me. 180. So what's the hybridization of that carbon? SP. SP, very good. And what's the hybridization of that carbon atom? SP, very good. Any questions on that? Okay.
