The last. Oh, you need protests. And this is in war. Conclusion of the you mean destructive in Billy Heidi Hood forming the idols they didn't know they go and CIA kind of water is ending. Do you believe that? Then you no better billet does on the night is in. That said this problem I won't. You may want who's carbon become? You have not lost you that is being done The boy they want more in Jordan. Then the next step the little bear attacks on this government Find the night and read intense little better in a province so that come, see And it's too every long they're here See things well, it on except the proclamation off people It's true list the minute I mean a wonderful hard his good skipping, signing nieces and more little mahonia from it Reserving in table dimensional They I did so they use of the warning off all year. No bombs. The I lose has to bind the brunt. Probably really only resourcing. This is
Okay. So I want to draw a structure for the ass cattle is dehydration of personal are super panel. So ask catalyze meeting. We're using a strong acid and dehydration while the loss of water, we draw the structure of super panel For Prince three Carbons. The ending is the alcohol. So carbon too. And it's done with usually sulfuric acid and he to aid in the process. It's the oxygen on sulfuric acid. I mean, of the alcohol as he is a pair of electrons to depart in eight or grab a hydrogen from sulfuric acid. I wish to. And this is a better leaving group. So what's that occurs? So this group is gonna leave and leave behind a carbon county intermediate, the secondary carbon Karen. And the method groups on personal propane act as electron density groups and during the electrons to make the positive charge more negative. So it's more stable than a primary carbon. Carbon. And sulfuric acid can behave as a base rather than that's how the carbon cat. and it's going to grab her. It's on from author of these carbons adjacent to the carbon head on. So we have three hydrogen on either of these carbons. And this is gonna be used to reforma bond, we know stable Akide. So in this case we can really just we get prepared for all this. But if we had a four carbon chain, do we have this car back out on? It would grab parts on from this carbon. These would lead to more stable, keen and this the sake will be more stable because we have more are groups we have to hear compared to Only one on purpose.
The reaction off. 16 17 with, I don't know, acetic acid. No different mechanism involved. Need you can. That means C x C h two. This is Yeah. We don't bear attacks. Explode. C o eggs, This attack, you know. Okay. Same to reaction, but good news. No. See Extreme. Yes. Yeah. Woman's parking. Mhm. It wants to do well, you know. Thanks. Yeah. So it's innocent reaction, right? Mhm sweet or minus.
So the first step of acid Cal eyes either. Cleavage is pro nation of the either oxygen to give in intermediate occitania my on which collapses to form an alcohol and they turn sherry Carbo cat ion So you will show that here so of h x is there his pops off here and we form, um, some intermediates. This will be plus X minus, and we also have the bond living off here. So then these will go back and forth, and this would even be plus a So there's an immediate um, but then these will work to form the product, which was the plus in age sex. So, um, the car broke had on with the loser proton before Manal Keen to metal protein. This is an example of the one elimination the acid use for cleavages often try floor ascetic acid
