Hey, guys. So I just wanna kick off this course talking about the relevance of organic chemistry. So hopefully, by this point, you've already had one year of general chemistry. So you learned about a lot of the atoms on the periodic table? Well, what is it about organic chemistry that's so special? Why do we take an entire extra year toe learn about organic chemistry? Let's go ahead and look into that. Well, basically, organic chemistry is the study of the chemistry of life. Okay, so what that means is that many of the molecules we're gonna be discussing in this course have to do with molecules that are made by biological systems That makes them really important to our lives. For example, you go to the store and you wanna buy some shampoo. I know all you guys have done this. When you look at the back and you're like, Wow, what are all these ingredients? I have no clue what's going on. Organic chemistry gives you the tools to be able to understand what's actually in a lot of the products that you consume. So, for example, Burt's bees very volumizing shampoo, I even increase included price there. I am not affiliated with this company at all. I don't even use it. As you can tell. My hair doesn't have enough volume. But whatever. I just thought this was an interesting example. Here we have four molecules that we may learn a little bit more about later. And as you can see, they could all be represented by these structures that I've drawn here. Now, you don't have the ability to fully understand these structures yet. We're going to get to that by the end of this chapter. Okay, but what's interesting is that organic chemistry really gives you a new lens to view the world through, because now you're gonna actually start to understand a lot of these Ah, lot of these forces that go into making these products are making food or whatever. You're gonna have to look at that and then just understand it a lot better. Another application just to show you how diverse the field of organic chemistry is completely on the opposite. How if we want to create something really destructive, like nerve gas, nerve gas, that has all to do with organic chemistry and actually has to do with like the way that organic chemistry reacts with the body, and that's what we call biochemistry, Right? Biochemistry would be the interaction of chemistry with biological systems. So this is not something that we're going to get to for a while. In fact, ever. This is something I learned in pharmacy school, but just want to show you guys how molecules like acetic acid, calling a pseudo calling these air molecules that are based off of organic chemistry interactive your body and actually could kill you like in 30 seconds. It's crazy how fast these molecules work.

So let's just go into recognizing what is organic molecules. So technically there's actually a lot of definitions on what is organic molecule based on what you're talking about back then. They used to have a much different definition. Some books will even say some, some things that are different. But the majority of the consensus is that technically inorganic molecules, any molecule that contains both carbon, obviously right, We know that life the chemistry of life is basically built on carbon, at least on the earth and carbon and hydrogen. Okay. The reason I said the whole Earth thing is because some people are like aliens are made out of like silicon or something. But like whatever the biology of life has to do with carbons. Okay. And then um, the an organic molecule that contains a mixture of hydrogen carbon only it doesn't have any other atoms would be called. You guys know that one. You should know that one. A hydrocarbon.
