All the hides, nigga. We are going to be naming this one right here in particular. Alright, step one.
Y'all niggas already know the deal. We gotta find the longest carbon chain first and foremost. Alright, so boom.
This is our longest carbon chain. We have a carbon right here, here, here, here, and here. Mind you, there is no carbon past this line that I drew.
This is only hydrogen. So we don't number that. Alright, this molecule having a 5 carbon spine gives the parent chain a classification of a pentane. But that's not the final parent chain name. I'mma show y'all how to name an aldehyde.
Alright, so boom. When naming an aldehyde, we drop the E at the end of your parent carbon chain and replace it with an AL. Like so. Alright, so look what I did here. I crossed out the E.
I took the AL from the beginning of the word aldehyde. We just replaced it. Boom.
Then we just dropped the P-E-N-T-A-N. You just drop it. Pentanol. That's it for your parent chain name. Pentanol.
Pentane containing an aldehyde. Pentanol. Alright, so now we have our parent chain name. Now, we gotta figure out where the fuck this shit is right here.
Alright, the substituent we have at carbon 2 is called a phenyl. But Vinny, this shit look like a benzene ring. Why is this not a benzaldehyde?
I'll show y'all right now. Alright, but before we do that, I'm gonna show you guys why my substituent is at 2 and not at 4. When numbering off substituents in a pentane, or any chain, containing an aldehyde, we start from the side nearest to the aldehyde. So in this case, it'll be left to right. If this was over here, we'd be numbering right to left.
live. So Vinny, why is the substituent called the phenyl group and this not named a benzaldehyde? In a benzaldehyde, we have a direct linkage from the benzene ring to the aldehyde.
So basically what I'm trying to say is if the aldehyde is attached directly to this cyclic carbon benzene ring, it will be a benzaldehyde. But when there's a bond or space or gap, whatever you want to call it, line in between the carbon chain and the benzene ring, we just give it a phenyl classification. That's just the rules.
That's just the rules. That's all you got to know. And that's probably as simple as this. gonna get direct connection here no direct connection here.
Alright so look benz for the benzene ring aldehyde for the directly attached aldehyde. Benz aldehyde so indirect attachment equals phenol direct attachment benz aldehyde. Alright so boom now that we know that we put our phenol right in front of the pentanol like this just like that Now this last step is crucial.
Before the phenol in the name, we have to list the location on the carbon chain in which it's located. So it'll be 2. Boom, this is the final answer. 2-phenyl-pentanol.
Alright, so look. 2-2-phenyl-phenyl. Alright, bet.
Cash is ripped. Pentanol. 1-2-3-4-5.
That's our pentane. All. That's our aldehyde. Pentane containing aldehyde. And a phenyl group at the 2 location.
Too easy, nigga.
