It's saving a little bit more energy, and that means that once again, my double bond is gonna be in the middle. Okay, The reason for that is that it has three orbital's that are overlapping, and each one is giving a little bit. Okay, now, the triple bond is actually gonna be the strongest. Okay, the reason for that is that there's only one region of overlap that is saving energy. And the answer is that the single bond is the weakest. So I already talked to you guys about this earlier, which of these is gonna be the weakest overall in terms of single, double or triple. Not quite as long, but not quite a short right now. Okay? And then you could guess that the dole von is going to be like the middle child. And actually turns out that because the triple bond is matter of one sigma into pie, this one's gonna be the shortest. Which one was the longer one? Do you guys remember? Sigma is the longest. Hopefully, you guys should remember what I talked about with Sigma versus pie. Now, you guys understand the only ones that rotate are the single bonds. And it's very difficult to break the bonds just to rotate. Double and triple their both not gonna be able to rotate because the fact that if you rotate them, you're gonna have to break them. And actually, that's what I want you guys to write for. All right, So what that means is that thes double bonds are not gonna be able to break. So what that means is that I'm gonna have to spend a lot of energy in order to rotate and break this bond, and that's energy that these atoms don't have most of the time. The reason is because remember that I said that when you form bonds, that saves a ton of energy. That's really unfavorable and really unlikely toe happen. What's gonna happen is that this top orbital, this top region is gonna break and this bottom region is gonna break. If I try toe rotate one of the Adams is that going toe break or change my bond at all And actually, yeah, will. So it's gonna look something like this where you have basically electrons overlapping at the top, electrons overlapping at the bottom. But they also have region at the top in the region of the bottom from the pi bonds. They do have that region of overlap in the middle, that one area. Now it's like a double bonds double bonds. It's always gonna have that bond present. Okay, because I can rotate one of the items as much as I want. Okay, so it turns out that for a single bond, since they only have one region of overlap, we're just going to write a big yes, right here. If I rotate this Adam, I can still keep this bond together. So if I just have one interaction in the middle where they're overlapping, is it possible to rotate one of the atoms like I'm doing right now and keep the bond intact? And the answer is yes. So remember that I said that a bond is just a region of shared space with electrons. Why? Because this has a lot to do with composition. So what that means is that a triple bond is made out of one sigma and two pi. But for a triple bond, now you have two sets of p orbital's on both sides that are overlapping, one up and down and one side to side. That's gonna be a still that one sigma from the middle from the S is. Now this is gonna have three orbit Orbital's overlapping with. All right, so overall, that kind of makes sense because the double bond has to orbital's that are overlapping. So for a double bond, it's actually gonna be one Sigma's always, because there's still one region of overlap in the middle from the S Orbital's okay, but there are also these P Orbital's and the P orbital's have two regions of relapse, so that means that a double bond is made out of a pie and a sigma or signal and a pie. They're the same thing when it comes to just if it's just one sigma, that's a single now, double and triple get a little bit more complicated because remember that I said that it's actually more than one orbital combining. Okay, so whenever I say Sigma, it means single single single means sigma. So I already told you guys, what single bonds were you guys remember? It's just made out of one Sigma. The first thing is composition, composition deals with Are they made out of single bonds? Pi bonds? A combination? We need to know this. You have single, double and triple, and what we need to know is just a few facts about each. So basically, we have three types of bonds.
