How many signals would you expect to see in the $^{1} \mathrm{H}$ NMR spectrum of each of the following compounds?

Problem Number 34 they have toe are vilified. There's bleeding Taccone on how many sickness that they will So in the human Kumble's which one is one 16 and this so is the signal discovered Now, if you look at this, uh, two problems here since the two sides one is on one side it is profiled On the other side is detail. These two are financial documents so there's need appearing in the same place. So one signal next against the Star Burns 16 on with C at three on the story here, which is S E. Let's look at this because you got this tool Here is when a symmetry govern therefore, these to hide things with a serious topic. They're Dia CEO Toby on. Hence they will appear Astute signals. We having two dependent intimacies German Mhm 19. No, this one This is snow again. This is eggs and eggs. The sun is come from the side and there is no other remedy government. So this will be nicer. Topic appearance A single a single one single. Next. I have a terrible headache team, but regular opinion it is they're neither nine short topic. No, they ask your topic. It LaPierre is a single one signal. Next is slow, immediately etc. 12 or three. This molecule that these have you wanna symmetry government. So where does one of this bill off? This Now here there is one symmetry govern. So these two problems with the that Syria topic hence they will be appealing Portugal's two things. The next component is building the small disc company that will produce that is the two programs in the actual topic. And so look here it has one signal.

In this question. Now off to deduce the number off Proton NMR sickness and in a more upsy 13 anymore signals produced by each compound. Given in this question to the first compound is an Atlantic Ito like it looks like this and bacon Stockett labeling the different types of blood arts year. So the tour metal groups on this side will be, um, having for dance that are equivalent three judges. I'm gonna leave a lot of them. A. Then the medallion group will have a different kind of proton and the middle group on the other end. You have different kinds of protons O as in different, a different kind of profound from everything as But those three protons will be couple into each other and are these two positions will have protons that are likeable into each other. In these two Britons were again be equivalent to each other. Average number 1 11 eat so I can get any harm. Five. Brought on an Imar Cygnus, and then you become the number off different carbons. These two will be one type of carbon to three. He it's more five six, some of so they have sure planets signals for the different types of carbon is present in this compound, moving on to the next. Combined. It's Ah, aromatic Esther compound again. There, protons in this corners on live on because it's a benzene ring, only one each. So we label the different types of protons. In this case, the three metal proton should be cool into each other. So we'll go make that Matalin brought on. And but they will be different from any other protons. I label them be something different, and the's do grow. Dunn's will be equivalent to each other. They used to be a government to each other, and this would be unique again we have. But he wrote on NMR signals and run the jewels. He find thanks seven c 13 and immerse Ignatz because off the seven different kinds of carbons. Next we have my mother, Mr which is a psychic from ground drop A sinking. Yeah, we have to hide regions teach corner because this is not a Benz in new. And if we label these I did. Gents needs to be committed to each other in the store will make on each other the studio become hundreds. So really stupid. So we have, um, four dives off high doses at the recognized four signals in the proton in my spectrum. And well, to t from five Cigna's in the See that in animal A spectrum. The next compound is again a cyclist compound, but it to eat and as we to write a general each corner again. So, in this case, the stool profound to be calling each other this to become into each other and so abilities to. So we have going to get the three brought on NMR signals And this carbon because this carbon and this carbon would be different. You have tool. So you thought in anymore Cygnus, actually. Are Amanda mistakes? These two types of five regions would be calling each other these tools and the students should be covering each other so we can label them both. Okay, on this ruby be And so we will have really to proton in our sickness in the next compound. Is there a site click? Hello. Deleted How to carve it. That hasn, with cloning best. Here. It's such a now world Hydrogen ian prejudices here to religion. See, so thies to ride regions would be equivalent to each other. So already still, but this it would be different. So overnight, even now, three pulled on NMR signals and burn too. Seiko Pain and Marsh signals. The final game ban is ah and Cain with two double bonds. You know, cats, German, nine other groups to use carbons. Didn't have hydrogen is attached to them. So here are all the meeting. Rodin's should be equivalent each other because this is a simicek structure. And these two make Diandra guns accident, um, protons attached to Al Qaeda groups. Um, that he had a teen groups on some, they will be equivalent to each other. So we have to go down and our signals. And there are three types off protons here. Generative Rodin's He's Oh, I'm sorry. Three carbons. Yeah, they met their carbons, which are all equivalent reach under. And then this Carvel, that is. I just ended the material groups and the double bond there. We complement each other. So that would be giving us to a second signal. These joke Arpels, working class to a third signal. So you didn't have three signals in the see guardian. In the more spectrum corresponding fidgety. Three different types of carbon is present in this compound.

And just problem. 1 78. We have to identify number of signals in Broken and Mark and she 13 animal For the Given Com policy, What's going bald is, uh, substitute the same blow beauty ch teau th day, that is. See the number of problems here there are three. So this will be one signal. This is too. But there is one problem. Three these two with theoretical on, uh, four. But these two will be are different because when this is up and this is down, there is still a topic. So this you'll get to signals here. So three or my I'm here also for play. Um, here, we'll get that also different. Does he do nothing? So, six, I am silly. So there'll be seven signals in of problem minimums in featured in a number. It will give one in 13 1 toe being or on a fight. So this will be these two will be a difficult All of this will be different. So they right See turning pigs in this molecule. The second molecule. See it, Stacy, it stay CST on PTSD. In this molecule, we would have one one. Then there is no problem here. This will be identical. Do on to the political on day. So there'll be three signals in the problem anymore. They 20 signals on one. So three on before or see third Internets 12 Hey! And for next trombone sequencing it Assists. He is now. Here. Is, um argue with the symmetry so we can expect. Yeah, we can expect this one. You have. Let's see, uh, this is one. This is since both the programs are on the same child. So this is to Andi. Uh, these two will be different. So three on before on here also three and four. So there before it's one signals and delegates off c 13 you have. Do you like me to everything? One one to you're I'm gain Be seated in signals. So three c third incidents. Next compound the trans off the same molecule. Seriously, Can CST now? Here we will have, uh What is he home? If we were quote, we will see. This is the sea and stay here. There is. This is C s three is on the other side. Now this here is a high reason. This is a reason. And this original theoretical and similarly these two I didn't will bear indican. So we will get Andy to see if you also will be in the same place. So we'll have one to increasing this. But it's one of the one. Any signals I'm 40 13 c 13 will have again. This is 11 This our water to on 33 sickness for C 30. Next one. Thanks. No, Since 12 since one to compound here again, we have oh brain asymmetry so that that should give it is look one one. Now we have the two problems on the backside toe on these two little Syria topic. So three, four and they for So there'll be four signals in a June and, um are on four c 13 and a more we get one here, one toe. Two. There are indications he and the 3 ft earning enema on next come home. 12 friends, 12 trends. Maybe this This first one This is trying to each other. Either roots are crimes, so we will have. It's one of the more. This will be identical 11 There is 22 What a grand nickel on three this really two different I feel Topic three I am just before. So there before x one signals on D C. 13, you have one to to ethnical on three de his three see third incidents.

Yeah. This question asks us to calculated the number off signals in the proton NMR off the five different eyes. Um, us off Hixon Oh, accent has this family last C six h 14 And there are for a vice a month off hexane. And, uh, I asked to get their mind how maney proton and them are signals. Each of these I similares will give rise to To draw on to this question, we have to draw the structures off the molecules. So n hexane is just the Lena Jackson which will start bitter ch three metal group and then going to see its two groups and then finally end with another CH three meta group. So this has Matile protons, which is going to be one type off proton, and it will give rise to on signal and then, uh, ch two protons right next to the middle. Protons have a different environment, so they are equivalent to each other, but different from the rest of the protons. So they'll have a specific signal, and then the juicy it's true. Groups and the sender have different environments from the rest of the protons, but are equal toe equivalent to each other. So they'll both her, um, another signal. So it has a B C three signals for this molecule. And the next weekend look at is you met them. Ben pains the tool, and then hardly that the ch three. So there are two metal groups at the end, and they're both be equivalent to each other, so we can mark them both with the letter A. And then the ch group has a hydration that will be different from any other hydrogen, so we can call that be. And then, um, this metal group at the end will be different. So you got that. See? And, uh, have to call this tea and eat, because the siege to here is I just sent to a siege group, and this siege to here is at the center metal group. So they will be different and non equivalent to each other. So we have a b c d. E find types off protons that regularized to five signups, and then we can look at, uh uh Did he meant there? Ben Dan. That will have omitted a group in one of the Sandra carbons in the centre carpets of the advance center Carbon and the metal group is in that. So this is called, um Do you met Do Brendan. And this has okay, one type of hydrogen and then these two are equivalent each other, so they have producing on their signal. And the CH is different from anything else. So that will produce a signal. And then the terminal metals will also produce a different signal that there be equal to each other so we can call them they. So this thing will have a BCG forcing us. And next we've looked at three. Isom was so fun. We have two more to look at. So next week and look at for diamond there by summer off vaccine hold the H huge team. This has been doing 3456 Cartlidge And then this has to Cleveland our own with their groups and they are actually equivalent to these. Also, there are terminal groups. B. Chavan wanted to r ch books of the article and each other, and then this will be does come type off hydrogen. So there's only going to be do cygnus for this compound which has the ups see name, um to three metal building. I'm sorry to three diamond till beauty. Okay. And, uh, last combined. We should look at is stuff. All right? I summer that has both off the middle groups. I won't do the same carpet. You still in this guest at three metal groups? Bound one carbon under day for five. Thanks. So this has three similar material groups. More in different meta group that is Addison Toe Associates to instead of carbon only and then see its to group. So this is you guys 23 signals. And this, uh, structure has the UBC name toe to diamond. There you can. So these are the structures and their corresponding signals. We discussed the name off the first arm from Bard. It's called in hexane, and, uh, this is God to make a deal pendant.
