Four atoms are arbitrarily labeled $\mathrm{D}, \mathrm{E}, \mathrm{F},$ and $\mathrm{G} .$ Their electronegativities are as follows: $\mathrm{D}=3.8, \mathrm{E}=3.3, \mathrm{F}=2.8$, and $\mathrm{G}=1.3 .$ If the atoms of these elements form the molecules DE, DG, EG, and DF, how would you arrange these molecules in order of increasing covalent bond character?

All right, But this question. We are looking at bond borders and bond length for a number of multiples. Our first molecule is, and they and we see this carbon carbon single bond. Remember, that bond order is equal to the number of bonds between Adams, so bond order, in this case is one. And if we look at our table carbon carbon single bonds are 154 extra rooms onto the next compound butane. We have another carbon carbon single bonds. In fact, all of these are carbon carpet single bonds. So we can actually just take our answer from part one and say that it applies to both structures because the carbon carbon bonds are the same. Bond orders one, and the length is 154 extremes that would move on to actually Kathleen is different from the other two because it's got a double bond in the center here to the bomb order is equal to two, because there to bonds between the two carpets and the carbon carbon double bond has a length of 134 hangs Trump's and notice that it is shorter than the carbon carbon single bond. So as bond order increases, bond length decreases, she had probably makes more sense of other areas over here, so bond order increases bond length decreases. Here we go. Okay, Our next compound is unsettling. So this is a triple bunt, and by now you should be able to predict that this chip a bond is going to be shorter. Can the double bond with single? So the bond order in this case is three because it's a triple bond. Three bonds and the carbon carbon triple bond has a length of 121 banks dumps, so it's less than the other compounds that we've discussed so far. Our last compound is Benzie. Now, when you go into a frenzy, you may see that there are double bonds and they're single bones. Remember residents. So in another universe, we're actually in the same universe, but a different resident structure. The double Barnes. There are different Adams, so the double bonds could be, for example, here because of residence. There's two possible benzene structures hand that means for a given carbon carbon bond. It has a bond order of 1.5 because let's take a look at this carbon carbon double bond. At first glance, you may think it's too. But if you factor in residence, so if I go back to this configuration of the same carbon carbon bond is a single bond with the Bund order of one. So we have to average the two residents structures, and the bond order becomes 1.5. You know, what about the bond flick? Um, the bond length should be in between the carbon carbon single bond in the carbon carbon double bond. So you may estimate that the bond length is up 144 eggs comes average of the two. Um, and that's not a bad estimate. Experimentally, it's been determined that the bonds length of carbon, carbon bonds and benzene is 139 x Trump's and that's end of the question. Thank you.

The first compound. Mhm. Yeah. Sequel. Age. See success. It'll poor See things. It's full. Oh, and the Air Force 1715 Yeah, 1715 Typically off a C or absorption. Then the cedar in animal rules eight. 18.5 the primary 18.5 being a primary, then 33.5. 40.6. This is the second regard, boy 40.6, which is a tertiary carbon. And then there is one week to 14 The continent is, um so the 214 should be a kid. A group. Andi. Uh, then we have a tertiary common meaning There should be to groups attached book on. Then there's a secondary government C h Two times. He extreme and, uh, see it stay and C at three. And it's so 336 Slovin nine. And quit. Yes. So these two is he a three on this is three period age in the interview? Yes. Should be appearing. Uh, 40.6. When the primary secondary that is 30 born client and baking blind place. The second companies Siebel extend home. Okay. Uh huh. Ir 1730 and sweet. happiness. Given 1730 again, it's a community group. Then Children amount 22.6 Primary 23.6 33. See it? Okay, I need to 0.23 point 6 to 3. But this ch then we have 52.8 a secondary C h two Andi do no 2.4 carefully to know too. 0.4 is Daisy. No, the humbled should be. Uh this, uh, 22.4 is a negative of carbon group, which is actually means being algae hide, so it should be in a limited proton. Do you have diarrhea? And, uh, C five. So one, 234 So that it was too. See trees, which are illegal Two. Yes, he does. Very little meaning there should be a test tool. Uh, C h two. We have people going six year and then we have a ch military once is C X 23.6. And attached to that there are two middle groups. See it. Stay on DSI it Stay which appeared at, uh yeah, 22 points. Is this and this? So the morning a bomb down the number of high dizziness 10 33 67 I am thinking so this is the structural compound. The third come home. See a physics bowl. She thinks it's a big for the i. R function is once it's 80 probably 20 people I expect they're going to get he don't featuring 22.9 25 point age. When did you born night? 25.8. Both a secondary 38.2 or so secondary. This is also the country C H two and then 1 29.8 1. 50.6 1. 29 0.8 1. 50.6 It should be doubled about the government's both the tertiary and, uh, 1 98.7. The Quaternary that is. See everyone for this is usually that is it is C h here and see it here now, looking at the values Jesus, it's a whole the spectacle of the gun home within. See? Uh huh. Now, the companies having well, uh, inside duration index equals number of carbons six minus number of high risen by two is four and then plus one equals thing. So the convention contain, uh, and he that we wants or three double ones. Pleasuring double bond plus bring equal to three. So you can write double one plus three. We go to think so. We have already assigned a CEO group. So did he say See, old doctrine on these two beats are I see everyone See? See it that we won't see it. They won 68 0. Yes. So now we have three ch two groups. So the possibility is a second gene drink and everyone's he I'm a Tito. Yeah, on the value matches this is a cultivated people. The i R value is 1680

Let's try Tetra Hydro representations of the following molecules for a We're looking at the two s three are an anti humor of to three dia promo Pantene And this would look like this here. I'm gonna start. Okay. I'm gonna call this carbon one here which would be ch three carbon too Harvin three coming or in carbon five. And we want to s so sweet PR age and three are so there would be our Tetra hydro representation And for be we're going to draw theme easel form of 35 obtained denial. So this can also be the musical form is also gonna be three or five s three are obtain. Okay, 35 dialogue. That's right. So 123 six carbon one carbon seven carbon three carbon five and three are what s there would be Tetra hydro representation of three are five as obtained 35 Dialogue measles obtain dial miso 35 obtained Dial

Here we are drawing some structures so fastly we have s. f. two. This is analogous to water. So, sulfur here has its two lone pairs, and each Florian has three lone pairs. Next we have S. I. Age four. So this is in fact analogous to methane scott S i H h h H in a tetrahedron arrangement. Following this, we've got a car box select acid, so we've got a central carbon double bond, oh, single bond alcohol group, finally a proton. Next we've got CH three S. H. So we have carbon hydrogen, another hydrogen, another hydrogen, and it was so far that is connected to a hydrogen here. All we have is to Lopez on the sofa.
