in this video, we're gonna discuss all the different things that you can make when you react a pneumonia derivative with the Carbondale. So at this point, you should feel pretty comfortable with the reaction of ammonia with the carbon. You'll you know that in an acidic environment, you add ammonia to a carbon, Neil, and you're going to get an Emmy Nitrogen, double bond. Carbon Looks like a carbon, Neil. Except it's a nitrogen. Okay, well, what would happen if instead of reacting with NH three, you take out one of the ages on H two and you replace it with something else? Let's say you replace it with another. I mean, then what would happen? Well, guys, this is where you get your Imean derivatives. Okay? So ammonia derivatives are gonna yield what we can call in General Imean derivatives because you're Imean derivatives. All look exactly like Emmy and accept that they just have different functional groups coming off of the nitrogen. Okay, so these I would commit that these two memory, if I were you because they're functional groups, you should know. And you never know if you're professor mixes it up. And instead of giving you a normal mean gives you, Let's say hydrazine. Then what happened? Wolf Hydrazine is the name of NH two with another. Any to okay. When hydrazine reacts with the carbon eel in an acidic environment, it makes hydra zone. Damn, that's confusing, Right? So hydrazine goes toe hydro zone. It makes sense the names of super similar, but make sure that you don't mix up the 21 easy way to think about it is that hydrazine and key tone make hydro zone so hydro zone would be the mixture of both. Right. Awesome. So what if you reacted with an N H two and O. H? Well, that's called a hydra Csilla mean, And that's going to give you a functional group called an oxen and oxen would be an enemy in with an O. H. Coming off the top. Finally, if you were to take a hydrazine, but put a fennel on it, that's a federal hydrazine, and you guys could guess it. Fennel hydrazine is gonna yield federal federal hydra zone when you acted with the Keto. Okay, so these air all different combinations that off follow the exact same mechanism as an Emmy. In addition, except that they're just derivatives of a mean that reacts to make a derivative of the Imean as a product. Okay, awesome, guys. So now I'm giving you a problem down here. Go ahead and see what you get. See if you can figure out how to react this big molecule with key tone, and then I'll show you the answer.

so there was a lot going on on that benzene molecule, but there was only one part of it that could react with the key tone and that waas the hydrazine. So this is just a derivative of hydrazine. Okay, in fact, this molecule is actually it's called 24 d n P, and it's actually used as Brady's test. So this is a molecule that you might actually use in your organic chemistry lab this semester, because it's a very famous test to test for key toned. What happens is that when you make the Fennel hydro zone product, that fennel hydro zone will precipitate out of the solution, and it usually precipitates like a yellow orange red color. If you get that precipitate, you have a key tone present. So this is actually a test that's used to detect key tones. Let's see what the federal Hydro zone product would look like. Well, we know that. I mean, obviously I'm not going to draw the whole mechanism because that's not what this questions asking, just asking to predict the product so I would go ahead and I would draw my I mean, but I need to attach the hydro zone part and the fact it's gonna be a fennel hydro zone. So I'm gonna add and h Okay, let's see what else attached to it. Well, we've got a benzene ring, okay? And that benzene ring has two Nitro groups. Let's add those and 02 and 02 and that would be it. That's your molecule. Okay, so this is basically a fennel hydra zone, right? Fennel hydro zone. And in fact, it's a 24 dying nitro fennel hydro zone. Right, because this is the two four Die Nitro part right two and four. So do you think you can figure out where the name comes from? It's 24 Die Nitro Federal Hydro. So that's why it's called 24 d N p. It's a great example of an Emmy derivative, and it's actually a reaction that you might see later this semester. So if it comes up, you'll say, Hey, I learned that at clutch. Maybe you could tell your lab partners that they'll know about clutch to, and more people know about us. Awesome. All right, so let's move on to the next topic
