So now we're going to kind of switch gears and move away from talking about strict addition reactions to talking about oxidation reactions. It turns out that double bonds not only can be added to, but they can also be oxidized. What that means is that they can be placed directly on them. Okay? So what we're going to talk about is some different ways to do that, and what I want to talk about right now is ozonolysis. Ozonolysis would be categorized as a reaction that is a form of weak oxidative cleavage. Okay? So what does that mean? Basically, cleavage just means to cut something. Okay? So this entire time we're going to be using our visual scissors to cut things, and we're going to be cutting things in different pieces. Okay? And there is a mechanism for ozonolysis. It's very long. If you guys need to know it for your professor, believe me, I'll teach it to you. But that's not going to be on this page. This page I just want to give you a general overview of what ozonolysis does. Okay? And what ozonolysis basically does is it slices double bonds in half and what it ends up making is a combination of ketones, aldehydes, and formaldehyde. Okay?
Why does it make each of those things? I'll explain. But think about it this way. Imagine that you have a very long carbon chain and there's one double bond in the middle, and you cut it into two. How many chains would you expect to have? Two. Alright. That's pretty easy. How about if I have a ring and I have a double bond in one part of it then I snip it right there. What would I expect to get at the end? Two rings? Two chains? No. I would just expect one chain. Right? Because I had like a ring and I cut it in one place, so now I have one chain. These are just like simple geometry questions that actually get students confused with ozonolysis. That's exactly the way this works. So here you can see I have a seven carbon chain with two places to cut. I could use scissor
