 So I guess this is an answer to that question that was the question that was Encountered on the last story asked on the last video Why Why is this one more resonance stabilized than the other one? Well, I mean it's a good question because we didn't try to do any resonance structures of this other one So let's try to do it. Can we push this positive charge onto anything else, right? So remember here We've got the two hydrogens Do we have any hydrogens here well carbon has that four bonds so no here no right So this carbon has four bonds this carbon has four bonds, right? This carbon is the only one with three bonds. You know what I'm saying So we can't actually push that positive charge on to any other carbon. So if we look here, right? What we can do is take a pi bond and move it over, right? So here we don't have a pi bond right next to that positive charge, you know So here we can do that and when we do that now we've created another The sp2 carbon right so essentially what we've got here is a series of these sp2 carbons in a row Right, so let's look at this. This is a good way to ask yourself. Can this resonate? All right, so we'll Mark our sp2 carbons with a little red Star okay, so that'll be SB2, okay, and we'll look at the sp2 carbons in this structure relative to this structure Okay, so let's start with this structure because we know it's not the right structure Okay, so if I point to a carbon and it's sp2 you tell me yes, okay, so that one is that sp2? Yes, right. Yes. Okay, so that one That one yes Right that one. Yes Right, so remember sp2 and Trigonal planar are like the same thing. Okay, so are these all these carbons trigonal planar, right? Yeah, so is that one? Yes Right, is that one? Yes That one. Yes. Okay, so all those are in a row, right is this one No, it's not right. It's tetrahedral, right or we call it sp3 Okay, this one is or not. Yes, definitely Right, that's where the carbocation is all carbocations are sp2 hybridized and what about this one here? No, okay, so you notice we have this Continuous ring of sp2 carbons and we have this one that's stuck out over by itself Okay, where there's this carbon in between right so here. Let's do the same sort of analysis Okay, so of course all of these are going to be the same so Let's just mark all those as sp2 carbons and is this one an sp2 carbon? Yes, very good, right because it's only got the three bonds to it, right? Okay, so is this one here? No, right. It's sp3. Yeah, it's got the four bonds to carbon. It's sp3. What about this one four bonds? So it's sp3, right? So you can see the apparent difference here and the structure, right? So we've got a continuous line of sp2 carbons in this structure That's why we're able to do these all these resonance structures Okay, so notice where all the resonance or where all the pi bond moves to, right? It only moves to in between carbons that are sp2, right? So ones that are have the ability to accept that pi bond. What if we tried to move? I mean we can't even do it, right? It won't even do it. Even if Even if you made this structure, that's I guess the last thing we should talk about, because even if you made this structure This intermediate is more stable and you can tell by all the resonance structures That if you made this particular carbocation, what would happen is you would have a one-two hydride shift Okay, so I'd like that. That, of course would make that structure there and then you'd be off to the races with that and then of course if you recall what the product was going to be The CO- would again Okay, is that cool? Let's erase this just so we don't confuse it Any questions on that one? Does that answer your question from the last one? Okay, good
