Right. So this customer doing structures first for to propose aqsa rain. So aqsa rain in just a kind of way that we describe having this three member oxygen ring like this. Oxygen obviously has the number one priority with the carbons kind of being two and three. So if you've got, uh, two pro Pollak Syrian on the same kind of purple groove off of one of the carbons s so I can just kind of draw this is having, like 123 I said, we're going to be, um, which I'm going to put down here now we have ah, cycle vaccine oxide. So, uh, how this is gonna be drawn is using the oxide kind of just plopping out on the edge just like that. Moving on to see We've got 2 to 33 tetra metal oxide rain again. This is an ox arraign. Meaning is that three member thing. We've got a 2 to 33 tetra ethyl, meaning that I just have to metals here and two metals there, and that's the entire structure. Then on to D, where the name is to tooth arms or to three epoxy to methyl pain. Tain um So what we're gonna do, actually is draw the pain Tain as the main chain since epoxy is named as a superstition s so we could have Yeah, Uh, 345 painting like this and under it in this weird kind of configuration because we know we have a 23 epoxy, meaning that two and three are both bonded to the same oxygen. We also know we have a tomb apple, meaning that that's gonna be out there. And that's gonna be structure of that.

Yes, sir. In this question, were given this compound, which is amino plantain, which has the molecular formula C five h 13 n, and were asked if I ng to tertiary a means so a tertiary amine which I will denote by this is going to have three Alcoa groups attached to it. So that makes our, um, nitrogen. It's going to be in the middle of this compound. So our first, um, possible I simmer for this would be this compound right here where our nitrogen is going to be in the middle, will have to methyl groups attached. And we'll also have ah, pro pole attachment three carbon. So 123 So, this compound, when we have a, um, the nitrogen in the middle, we're going to name it according to the Alka groups. And we're gonna name the Alka groups as attachments. So this is going to be an end, um, dime Ethel, because we have to metal attachments. And this is propofol a mean so an end just means that we're bonded to the first carbon. So for our second ice immer our nitrogen again is going to be in the middle this time. We're going to have to Ethel attachments. So to attachments with two carbons. So 12 and 12 and we'll have one metal attachment. So this is going to be an end di ethyl metal. I mean, So these are our two ice MERS for our tertiary amine with the chemical formula C five h 13 n.

Okay, so you get the formulas for song structures. The first one is to method Vietnam said the um butane is four carbons, the l anything positive galahad. And because we only have one number for the metal group, it means the odds at the end to draw the outer head first, just like that. And we've been method on carbon too. The second one is para myth. Oxy Benzene to hide. No, I'm sorry. It should be a criminal sir. The A. L. Again, why we have been out ahead and propane is three carbons through carbon outside. Next one is pf oxy Benzene galahad. So the P stands for para and it's four carbons away from the Orthodoxy group which is an auction attached to an ethyl group which is an ether. So Ben's all to hide is I mean yeah, Ben's all to hide is a Benzene ring attached to an AL to hood and Ben's during a six carbons with Australian double and single bonds. So here is the alcohol attached the benzene ring. Ben Zardad and then four carbons away. 123 and four is getting Mediafax group oxygen bound Sue and ethel. And this example of ether, okay for Dave, we have beauty noon and um the ending in positive cartoon because there's the number, there means the cartoons at the it's on carbon too because it came down carbon one otherwise have been out ahead. Yeah, this is also called to be at noon. And then first to I mean for e we have Bruno purple noon you in the urn giving us a cartoon for paints, the carbons. So it must be on carbon too. It can't be all one or three being outside. And the Birmingham is on carbon other carbon one or through it's a trauma purple. At first he was the key to the carpet too. And you can also call this one bergamo to permit in. Can you get the position of the government? And the key tune X one is to afternoon happiness seven carbons. The tone is the key to and in this case we have to give the number because it could be on this carbon this one, it could be on carbons three or four. Do you think of the number where it's located? So it was on carpet? Three of you? Three Hampton Inn. Next one is um so in the model we only have three carbons and that's characteristic of european. So it narrows down to B and E. And for E we have a burning attached to one of the carbons. So in the structure we actually have um dial which is an alcohol or to alcohol in the same structure. So the um the only close structure to resemble us would be personal and bergamot Perpignan Sabeti. And this is for um. G soon the reality looks like this. We have a three carbon sheen with alcohol is on carbons, wanted to, and then there was a dial, so it only matches BND because it has three carbons. Other than that, it's not the same structure.

All right. You want to write the four mills for long structures? The first one is to metal Vietnam. So I think it helps to write out the line structure first and then we're at the Formula second two. Butane is four carbons. The ale ending positive Inada Hood because we only have one number for the method group, it means the adenoids at the beginning or the end, it's at the end of the chain. So if we draw the four carbon out ahead first, putting the out at the end, earth front, it's gonna be the structure method on carbon too. And um going from left to right, we're gonna have C. O. H. And the second carbon is ch CH three. And this is found an ethnic group. Ch two, series three, the second one, we have um personal super pains, three carbons, the ale giving us an out ahead and this will be ch CH two, see it through. Percy we have um P foxy bends out hard, so Ben Zelda Hyde is an AL to hide attached to a benzene ring and a Benzene ring is six carbon ring with alternating double and single bonds. It's just like this, you may see it like this to the circle that you can out how attached to this for Ben's out ahead and then the P means para and this is four carbons away from the alcohol functional group 123 and a foxy is so f minus two carbons. A fox season either with an oxygen attached to an ethyl group. So I think that and um Superior has won four medals, won three and Ortho is 1 to 1 discussing benzene rings. So the formula for this, if we you have six carbons in Benzene. And um so if we give from left to right, start with the ethyl group beyond siege through siege to oh then we have no Hodgins on this carbon C. Going clockwise X one is ch ch and then see C. O. H. For the al to hide and they continue to go clock was this one is Ch and the last one is safe as well. So in total we have six in the ring and two carbons in the ethnic groups 89 for the out ahead, it's B. C. Nine 123456789 And then we have three options to 567 89 10 H 10 and um, one 22 auctions get that every day. We have used the beauty known to the own ending in positive key tune and between these four carbons. So it has to be on carbon to because it can't be on carbon one otherwise been out ahead. It's also called to butte dude, it's like that and the formula is see it through Ceo CH two CH three for each we have before um a proper noon per penis three you in any positive cartoon. So it'll be on the carpet to and burning on uh carbon three. So you can also call this three Burma super pitted. And the formula for this is H through Ceo Ch two br. And then for F, we have two afternoon have 10 to 7 carbons, the own mosquito. And in this case you have to indicate where the kitchen is because it could be on carbon three. Therefore, so the formula for this is Ch through Ceo and we're gonna have 1234 C. H. D. S. Ch three. And then the model it shows um actually shows the dial which is to alcohol on the same structure. So it's not any of these, but the causes resemblance would be personal and Burma purple noon because each have three carbons in european
