 Okay, so this one says, draw all important resonance structures for the following molecule. Or I, I guess. Okay, so resonance structures. How do I show resonance structures? The motion of two electrons, right? We're going to show it with the curly arrows, okay? So, and how do I show what's the resonance arrow look like? The double headed arrow, okay? So, we're going to show that to indicate another resonance structure. Okay? So, do we have any electrons that can move around in this thing for a resonance structure? Which ones are they? The pi bond. The pi bond electrons. So we have some here. So, to do one resonance structure, let's just do one. The positive charge here, what does there have to be over here? Negative charge. Positive charge, right? Yeah, don't just say what somebody else is saying. Yeah, same charge has to be on both sides of the arrow, okay? So is that the only resonance structure? No. There more? Yeah. There's a ton more. You can make a ton of those. Where's the positive charge going to be here? The last pi bond. The corner? Yeah. Is there any more? Yeah. Should we do another one? Yeah. Like that? Is that good? Yes. Okay. You can move the lone pair outside, right? There is no lone pair. I mean, not yet, right? Not yet, but we're going to do one of those two, okay? Okay. We'll make one of the pi bonds a lone pair is what you're saying. Yeah. Yeah, yeah, yeah. Okay, cool. Let's see if we're still on. So these would be the more major resonance contributors. Then of course, like Sheldon was saying, we can break up some more of those charges. Like for here, if you want to, which pi bond did you want to move? Any of them? This one or this one or this one? Okay. Should I just do one and see if you got something simple? The bottom one. This one here? Yeah. Okay. So let's draw that and show another resonance structure. So what we could do, instead of moving it back over there, which would be this resonance structure, we could instead take these electrons and move them outside the ring as a lone pair. Okay? This is going to be a very minor route of resonance structure and you'll see why and I want you to tell me why. Yeah. You've got that charge separation and that high amount of charges. Okay? Both of which are met. Of course, you could do that with all of these. You could move them all, break them all up. And then you can do it all at the same time. Yeah. That's a resonance form but a very, very minor contributor. So for just, I put that away for example, how many of these were you actually looking for? For this one, I wanted you to just draw as many as you wanted to. I think for an example, you'd say three maybe. And out of this, what would you choose for the major and the minor ones? Obviously the one with the multiple charges would be the most minor. I mean... When the second one would be the most major. I would say that the ones within the positive charge within the ring to be the more major ones. The reason being is because carbocations that have more carbons associated with them, so like a tertiary carbocation, is more stable than a secondary which is more stable than a primary because carbon has more electron density to donate than hydrogen does. Okay? So since there's two carbons here, right, that's going to be more stable than just the one carbon being donated. Okay? Yes. So the more, the one that's contributing the most to, like I was saying, you're going to want to look at no charge separation, so this is no good. And the one that has the most carbons around it. Okay? For the positive charge. The more charges that's the worst it can be. So that means like they have one positive charge that they have, like, different have more carbons and they will have more stable. More stable. And if you have a heteroatom next to that positive charge, then it makes it even more stable. Okay? Like an oxygen. Okay. Or just that would be significant. Least significant. Least significant, yes. Or the minor contributor is what you would say. Of the three on the top that just have one charge, which one's the most significant? Well, yeah, the two on the, I mean, these two, these two, for the three on the top, I would say I would want you guys to think these two are equal. And this one is less significant. Right, because the carbons are around. Well, because there's two carbons connected to the carbocation as opposed to just one carbons. Okay? That's what I was getting at. Not that it, because it's a cyclic structure. It would be more significant than that one. Yep. Any other questions on this? I think we killed it.
