In this video, we're discussing a tri Acer reaction in the form of oxidation. Now, under this type of reaction, we're gonna say that elemental oxygen 02 cleaves pie bonds to create carb acids. So if we take a look here, here go our pi bonds in our original triglyceride molecule. And if we look at them, what's gonna happen here is we're using atmospheric oxygen, elemental oxygen. It's gonna cleave these P bonds. And here just for color coding, these three double bonded carbons are these three double bonded carbons and then these three would be these three, I basically just cut them apart from each other. They still have their double bonds. But we're trying to make carbolic acids now. So these carbons to make carboxylic acid, they're each gonna double bond to oxygen and to make it a carbolic acid, they'll also be connected to an oh group and same thing on the other side. So in that way, we created carbolic acids from our original double bonded carbons. So that's the basis of this reaction. We're using environmental oxygen and atmospheric oxygen 02 to cut or cleave the pi bond in order to create two carboy acids from the place where it's cut the pi bond that's cut. Right. So, just keep this in mind when dealing with oxidation of a trio glycerol or a triglyceride molecule.

Here, it says, determine the products created under the following oxidation reaction. So remember in this oxidation reaction, we are cutting or cleaving these py boss and where we cut, we're gonna get carbolic acids. This last chain here doesn't have a pi bond in, in terms of the carbon chain. So there's not gonna be a cleaving that occurs here. So here we're gonna say that our product at the end. So have this portion and we have 24682468. Then we'd have this carbon that's double bonded still, but it's a carbolic acid. Now plus this portion here, which is a carbolic acid and then we're still connected here and we're gonna say we have this oxygen and then we're gonna say we're gonna cut here plus we have here. So everywhere, everywhere we have a P bomb, we're gonna form a carbolic acid. So we're gonna have, this comes a Carboy acid, this this and this. So this one's a little trickier plus this last portion over here. And then here we have this final portion that doesn't have carbon double bonded carbon. So we're gonna keep this chain intact. So now give us our final answer. So we can see that we have this whole piece here and they're gonna have these pieces over here as the other portions. So this one gives us a plethora of different molecules based on this oxidation reaction.
