Suppose we want to synthesize this key tone by using Dhi Qar box elation. Well, how would we go about doing this? Well, we know that one of the starting products must have heat must, uh, heat. This really depends, but tip depends on the molecule, but typically it's between 101 150 degrees Celsius. But we're just going to denote it has a triangle labeled as heat and well, another key aspect is that it must be Beta Carbonell, which basically means that whatever we're trying to get rid of, if it's d card box elation, which means we're heating a Carmack Selic acid that also has another carbon eel in the beta position, which means that we had our carbon carbon, the carbon adjacent would be Alfa and the carbon next to it would be beta. And that will be what we're looking for is beta Carbonell. And if we're starting or if we want to make a specific key tone will call that are beta carbon eel and, well, keep in acid. Right. So the question is, what can we use? Well, we what we can use for the 1st 1 is quite simple. we can make this our Alfa Carbon or we can make that one. Or Alfa Carbon doesn't really matter that much. I'm just going to take this one and just out of car books look, acid. Because when we had heat that car books, like, ask you, I would escape as carbon dioxide gas. How about this one about this example? Well, it would be quite similar to the previous one. We would try to determine what power? Uh, beta carbon carbon would be. We would It would need to be an acid, and it looks like we end with an acid, so it'll have a die carb oxalic acid molecule has are starting material. And, well, we really only have one option for Alfa Carbon. So people draw our molecule once again and just connect. Now, if a carbon pretty straightforward, right? How about this one? Well, once again, we have two options for an Alfa carbon to add a carb oxalic acid to we can have this one or this one in this molecule. Both these carbons are identical, so we can pick either one, and it would be perfectly fine. Let's just pick this one. Alfa Beta so we had heat that escapes as carbon dioxide and our cyclo hexane on. And finally, how about this one? Once again, we are making another acid. So we need to start with a dyke. Are bookseller gas and molecule Then we only have one option for our Alfa Carbon. We had heat and we have our products.
