I quickly just want to touch on the diacids. Anytime you have 2 carboxylic acids on the same chain, it's called a diacid. You might want to know the first three most simple diacids. The first one is called oxalic acid. The second one's called malonic acid. And the last one is succinic acid. These will have varying levels of relevance this semester. Malonic acid is huge. You're going to hear that a lot. Oxalic, not so much. Succinic comes up a little bit. The biggest thing is just these might come up so you should know at least the 3 most simple ones. If you'll notice, they start off with the letters O, M, S. I was trying to think of a way that you could remember them and then that took me back to that South Park episode where Cartman goes like 500 years in the future and it's a bunch of atheists. And instead of saying, oh my God, they say, 'oh my science' because they're like, you know, so godless. And I think that's perfect. So now you guys memorized it. That's not leaving your head, right? Oh my science, Oxalic, melonic, succinic. All right? Perfect. Let's move on to the next topic.
