So hopefully what you said was that letter 'A' is definitely organic. So I'm just going to put an 'O' with a checkbox, and it is because it's made out of carbon and hydrogen. Perfect. Is it also a hydrocarbon? So, I'm going to put the smallest form of carbon called methane. So you might know methane smells bad. It's released like in gas, so sorry. Too much information. But whatever. That is an organic molecule.
How about this next one here? Hopefully, you said that yes, this is organic. Because once again, it has carbon and it has hydrogen. Is it a hydrocarbon? No. This would not be a hydrocarbon. The reason is that it has an oxygen there. See how I have an atom that is not a carbon or a hydrogen? So that means that this is considered just an organic molecule. In fact, this is acetone. So if you, maybe you women use acetone to take your nail polish off, whatever, I hate that smell. It's disgusting. That's what the molecule looks like. We're going to be learning about a lot of really cool molecules. At least, I think they're cool. I have to think they're cool. I'm a tutor. But they are really cool. Hopefully, you'll get to know them too. Don't memorize these names yet. I'm just giving you some information for later.
Then finally, this last one, hopefully, what you said is that this was not organic and also it was not a hydrocarbon. The reason is that I do have a carbon here, but I do not have a hydrogen. There are no hydrogens, so this is not an organic molecule. In fact, this is what we consider can be a little confusing, inorganic carbon, like not organic. This would be a form of inorganic carbon because it doesn't have any hydrogens at all. In fact, this is CO2 or carbon dioxide. So carbon dioxide, you know that's like a greenhouse gas. It goes into the air. That's considered inorganic. We would learn about this a little bit more in gen chem because it has to do more with inorganic and then for organic, we would deal more with the molecules that have hydrogens on them. That's a general rule.
