Okay. So just to describe the difference between an alcoholic and a cartoon. So now to hide is um found at the end of carbon chain. This could be either in a ring or a straight street, a street chain hydrocarbon. So if we had personal this is an alcohol. He was Ceo H. And the next carbon is CH two ch through mm hmm. And this is called ethanol. I mean uh Personal busy with three carbons. Another example is um just just don't get the carbon chain. So we had five carbon instead of three 12345 And the a lending positive childhood. Is this gonna be fentaNYL? And the formula for this? Again, C. O. H. Is characteristic of the alcohol functional group. We have three C. H. Two S. Something like this. And then a series three. Okay, so the next one is um describing a key tune. So let's see the same structure Gregory cartoon and upside down. So this would be called purple noon instead of two permanent. Because we couldn't have the key tune on carbons one or three. These otherwise been out hired. Who wouldn't have enough violence. So if you see it on, if you see it like this inside, the chain could be key to. But if we had the structure, you have to indicate the position of the key to him because it could be on carbon three as well. But carbons two and four are the same. If you just turn structure around this would be to Vietnam and if you're on carbon three would be through Vietnam to the N ending and positive Akita. It's another example of an Al Fattah cartoon which is again a straight chain hydrocarbons but can also be a ring as long as it's not aromatic. So you're just a beautiful and so B. Ch I will have to see H two S. 63 Don't be that within an example of a alphabetically tune. So I'm going to do three beaten instead. Yeah, different aromatic structure. You can use the benzene ring as template and aromatic referring to being a ring the same plane and having a candidate system of alternating double and single bonds or a pair of electrons that can simulate a third group but also following huckle huckle rule, which is foreign plus two electrons in this ring. We have each of these carbons sp two and sp two hybridized carbon as one pilot tron to have two year to year to year. We have 16 total and is going to equal one and an example would be Ben's out ahead. Probably this common. So we can also add some situates to the alcohol as well. Another example using the Benzene rings template and with the out ahead here and put a halogen the Ortho position, which is 13 I mean 12 from the outer hood and we can also put in alcohol in the the 1/4 position. So this would be a pair to the outer hood and some examples of in a aromatic you tune using the Benzene rings Temple again said it, good example is set for noon and then keeping the seat if known and adding, I guess this seems substitutes or instead of brown, you can add chlorine but really just anything that changed a little bit and um actually I'm gonna put alcohol, we're here. So the outer hide is a um it's actually out ahead of the kittens are many directors so it's not really realistic to have the product in the Ortho position, some changes around. So again, meta is 13 from the outer heard, 212 Pretty challenging here and um, already and then the same thing for us to it's putting an alcohol here and instead of Birmingham just declaring. So the first one is Ben's out ahead and it's going to be three burma because it's three carbons away from the outer hood and this one is going to be sarah placing the brimming with chlorine for this one and this will be three hydroxy, it's indicating alcohol and he's out of her.
