everyone. So we're gonna start off this course by first talking about the relevance of organic chemistry at this point, you've taken the course is necessary in general chemistry where you learned about the different concepts such as the elements of the periodic table. So Akiyama tree tight rations. Even electoral chemistry, the good thing is the majority of this information is not really gonna transfer over to organic chemistry. There's only gonna be a few concepts mainly around like periodic trends that are going to carry over from Jenkins right now. Don't worry about them too much. We'll cover them when we get to those ideas. Now, back to the relevance of organic chemistry. Well, organic chemistry itself is the chemistry of life. It consists of the study of molecules that are typically typically created and used by biological systems. So, organic chemistry is important because it involves our everyday lives. If we take a look at this first image, we have the ingredients of a hairspray bottle and I've zeroed in on four organic molecules that are found within the ingredients right now. These molecules don't seem like anything you might recognize. You don't know the number of elements housed within each molecule, but you'll learn about these kinds of ideas how to interpret a molecule like this later on, but just realize right now that something as simple as a hair bottle is heavily involved in organic chemistry. Now there are some destructive applications to organic chemistry here, we have the creation of nerve gasses. So here, I've circled acetylcholine acetic acid and choline itself. These organic molecules are interacting with a biological system here, this is a way of showing how organic chemistry is the chemistry of life. And we're talking about how chemistry interacts with biological systems. That also branches off into what we call biochemistry. We're not gonna delve too deeply into biochemistry, but just realize that biochemistry is kind of like an offshoot of these organic chemistry ideas that we're going to discover and talk about this semester. Alright, so for right now, just realize that organic chemistry, although new to you, is highly relevant in this course and in everyday life.
Household products have tons of organic molecules in them! It feels awesome when you know what they mean.

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 on 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 hydrocarbon.
Organic Molecule: Any molecule that contains carbon bonded to hydrogen.
Hydrocarbon: Any molecule that contains only carbon and hydrogen, and nothing else.

so hopefully what you said was that number letter A is definitely, um organic. So I'm just gonna put in Oh, with a check box. And it is because it's made out of carbon and hydrogen. Perfect. Is it also a hydrocarbon? So I'm gonna put h Is it also a hydrocarbon? Yes, it is. Because it on Lee has carbon and hydrogen. In fact, this is the most simple, smallest form of carbon called methane. Okay, so you might know, like methane, like, smells bad. It's released, like in gas. So sorry, too much information, but whatever, Um, that is an organic molecule. How about this next one here? Hopefully, you said that? Yes. This is organic. Okay, because once again, it has carbon, and it has hydrogen. Is it a hydrocarbon? No, this would not be a hydrocarbon. The reason is because it has an oxygen there. See how I haven't Adam, That is not a carbon or hydrogen. So that means that this is considered a This is considered just an organic molecule. In fact, this is acetone. So if you guys, maybe you girls use attitude like take your nail polish off. Whatever. I hate that smell. It's disgusting. That's what the molecule looks like. All right, We're gonna be learning about a lot of really cool molecules. At least I think they're cool, right? I have. I have to think they're cool. I'm a tutor, but they are really cool. So hopefully we'll get to know them too. Don't memorize that. This is don't memorize these names yet. I'm just giving you some information for later. Okay, then finally, this last one, hopefully you guys said is that this was not organic. And also, it was not Ah, hydrocarbon. Okay, The reason is because I do have a carbon here, but I do not have Ah, hydrogen. Okay, there are no hydrogen, so this is not an organic molecule. In fact, this is what we consider. It can be a little bit confusing in organic carbon, like not organic. This would be a form of inorganic carbon because it doesn't have any hydrogen at all. In fact, this is CO two or carbon dioxide. So carbon dioxide, you know, that's like a greenhouse gas that goes into the air that's considered inorganic. We would learn about this a little bit more in gen cam because that has to do more with inorganic. And then for organic, we would deal more with the molecules that have hydrogen on them. Okay, that's a general rule.
Orgo isn’t so bad, right? Let’s move on to the next topic.
