00:03 like everybody here. Yeah, I have to remember that. Everybody

00:13 everybody's right. Yeah, yeah. . If anything it takes to do

00:58 you tip here this new freight. . My class, pretty sure.

01:25 . Yeah. Does everybody understand or everybody know? Oh, thanks for

01:51 . Nice. I Yes. After . Okay. Mhm. Right.

02:42 Oh, you look. Thank See what? Yeah. Yeah.

03:01 huh. Yeah, he was What trouble? That's good. It

03:21 different. Your pt. Yeah. . Okay. Okay. Hello?

03:53 Who is this about? What I've told? Yeah. Yes.

04:11 Right, Okay. Yes. Mm . It's happening. Uh huh Oh

04:34 , yeah. Quick. Mhm Mr Uh huh. Mm Yeah.

04:51 . Thank Yes, sir. patient. Thank you. Mhm.

05:06 . What? Okay. Mhm. the one always in the same

05:25 Yes. Okay. You made let it. Yeah. You tell

05:37 . Yeah. What uh maybe you say that the top position. What

05:45 that be really? These were It's true. That makes a

06:03 You 12, Yeah. Or C . Mhm. Right. Yeah.

06:19 huh. He's coming around. Everybody safe. Yeah. Oh.

06:36 . Yeah. Remember data. We started that. Oh yeah,

07:06 . Some of the team start. . Ready. Oh, purpose.

07:25 God. Yeah. Yeah. So Uh huh. Okay. Century.

08:56 . Yeah, we're great. He do the proper group. What?

09:31 bird? Yeah. Yes. Yeah. You've rotated. Thanks.

10:02 is mm First. Yeah. Yeah. Thank you. Yeah,

11:06 me. Thanks. So sorry. . Right. Right position.

12:01 Each. Mhm. The okay. . Mhm. All right,

12:59 Uh huh. Start. Yeah. it's in a box? All

13:55 Yes. Yeah. So, cyclops this missile psycho contain die missile cycle

14:28 mhm. Cyclo vaccine. Right. the missile site vaccine, there's no

14:36 way to need me. Oh, they didn't even need to do

14:53 Right. Yeah. Mm hmm. . So this would be dimethyl cyclonic

15:03 . Right. When I have two like that, they're called Nicholas becca

15:19 gasoline. Why? Because Natalie is very common compound. The solution is

15:27 Benzene rings fused together. Let's Okay. Mhm. Okay. And

15:54 have saturated. I would call it . Thanks. So, with

18:20 it's just okay, remember. Okay. Oh, yeah. Are

19:35 these considered aromatic carbon compounds? explain your answer. Unsaturated. All

19:49 . Yeah. Yeah. Oh, . This segment guilty. Mr What

20:21 a Mhm stretch marks. We'll Yes. Or Yeah. Okay.

20:44 you. Mhm. Yeah. That is a bureaucratic farmhouse. You

22:32 these are also called circle. Yeah. Yes, Yes.

22:51 So they believe similar laid out. . Thank you. All right.

23:25 . Yeah. So, did I an estonian structure? I didn't join

23:33 . The instructions in a thrilling structure be similar to this. Except it

23:40 aromatic. In other words, there a saturation. Can these brings Can

23:48 draw this for me since my hand not helping me. Can somebody go

23:53 the board and room? Uh, the decline, but Uh huh.

23:59 compound consisting of two aromatic rings fused naturally. Yeah. Yeah.

24:12 Got it. Got it. You guys you see what you

24:42 That's true too. Yeah. That's the critical thing. Critical thing is

24:49 all the carbons are satisfied with hydrogen another car. Okay. Tika hydro

25:08 Lynn. She drew in a cell structure. And you see why that's

25:15 Nastily if I put hydrogen is in with these double bonds, it will

25:28 the car. Hydro naturally. I inherited the name Nafta Lynn but it's

25:44 completely saturated. This is not insulin . It's an aromatic structure. You

25:53 it's two aromatic rings fused together. an aromatic structure. It's unsaturated and

26:00 structure. Yeah. Okay. That be left. If I put hydrogen

26:18 in place of these double bonds. deca hydro necessarily because this by itself

26:30 naturally if I put hydrogen to replace those double bonds will be deca hydro

26:38 Hi prison. Not really aka hydro . So Benjamin told you me gasoline

27:01 they name the molecules by virtue of different groups. Have that easy.

27:21 , certain treasures. Mhm. The is what's important. So you've got

27:35 necessarily right. If I saturate all carbons with hydrogen cycle. Take out

27:49 the feeling these are all liquids. huh. Because their boiling points,

27:59 are they liquid at the surface the points parents. If there is to

28:08 in principle, I need to go . I think it was dramatic.

28:15 be here. That's just what? , no, it's uh, an

28:24 compound is defined by its own Okay. The fact that he spends

28:32 doesn't spend, it has nothing to with it. Yes, it was

28:37 great. Yeah. Benzene is very actually. I can smell it.

28:44 I have a leak in the Can I can smell it? Because

28:49 haven't been seen. Yeah. Have broken bottle of benzene or very

28:58 flammable. They're all flammable here. Fire has it's a fire hazard for

29:15 . What we were talking yesterday about companies keep these samples of the

29:23 hydrocarbons. Aromatic hydrocarbons. Just is creating killing their Yeah. You wear

29:37 wear masks right. When you he handling cuttings to you? I hope

29:42 do. Yeah, It should be point right now. We only

29:50 Well, that's true because of the , but yeah, let me we

29:57 , wow. Yeah, yeah. have a core lab or you have

30:04 lab in your belief. A core . And so it's down there.

30:17 . Yeah, cuttings. Yeah. , a photographer wants to do some

30:29 on things. Yeah. Who's gonna custody of both of those sentence.

30:46 . All right. So is the clear guys. You see why this

30:56 called method cyclops maintain, Right? contains structure with a missile group

31:05 Right. You know what it is ? The diamond side. You know

31:17 it's called cycle of plantain. You know what it is called psycho

31:25 to enter cycling right? Cyclone and . You know why this is called

31:31 cycle ability mason. Such lapentti like group connected to the south side to

31:43 structure. So this is the sacrament structure. This is metal sacrament sacrament

31:50 with the metal group. This is complete with two muscle groups. Die

31:59 And when I don't refer to them position, just diamonds. Okay,

32:07 I if I put this metal group instead of here now I have another

32:14 problems. Mm I have a nomenclature . So I'm going to call it

32:23 three Because this 123 1 3 I right. You see what I

32:35 once every dime inside. I don't to call it 12 Dimethyl rain.

32:44 is one proven method. Right? I don't need to call it that

32:49 a name. I'm aside Cyclo 20 . Nobody can make a mistake when

32:56 put in dimensional sacramento. If I the method group to another position,

33:02 I have a problem. Then I to be specific. Pulling it one

33:09 . So 13. Yeah. He if I put it here, is

33:35 really any different? He'll be Yeah, it's unique. Okay,

33:55 this is cyclone. Hexi. This method side to vaccine. I have

34:00 when I have another metal group. have to be specific now. And

34:05 have to put it one, two . I'll cyclo X A. If

34:15 put it here, I have to it one three. Mhm. What

34:25 I call it? Is there any if I put it here or

34:36 Would there be any difference in that ? It's the same, isn't

34:43 And then you have the Decca hydro derived from the word naturally. Last

34:50 would be two Benzene rings. There'll some double bonds here in some double

34:58 here. Two benzene rings fused They're called. Last challenge. And

35:04 this is a saturated structure, I it deca hydro last challenge. 10

35:11 atoms in the natural in structure. if it's not clean, it's

35:22 Yeah, deca hydro to be saturated hydrogen. Okay, so can you

35:36 the devil bones here Double one. bond double bond, yeah, contributed

35:45 bonds. So this is benzene, unique structure you can call it nothing

35:52 but Benzie. Okay. This is you in structured by virtue of this

36:00 , proof. Told you me. . What is this call you guys

36:21 ? I have an ethyl group. . What? Right? Yes.

36:32 indeed for saint sl Benzene, is any way to structure other than this

36:39 Benzene? Can you dream of Two make a S. I'll Benzene

36:48 different from what you see there. could be silent. What?

36:56 no, let's not put into Uh, into into uh structural

37:05 Just the nomenclature. Who? So is really because there's two methyl

37:22 So without this it would be Halloween this. It will be easy.

37:29 . And because the guy that two groups are adjacent, I call also

37:37 and call this meta xylene one metal here Skips one another method group we

37:47 called meta xylene. If the if method group is exactly opposite of the

37:56 method group, I call it Ara . Right. So or so?

38:08 methods. Ali Sarah Riley. All right. So Benzene toluene.

38:16 . Asyl. Benzene two Methyl groups to each other or call it Ortho

38:31 to method groups. Yeah. In configuration the methods alien. two medical

38:40 in this configuration called para. All right. Mhm. Or I

38:49 have a branch like this. whereas this called xylene, this structure

38:58 be included to me. What else you call the structure by the

39:11 That's good. There's a method group in the middle group here. It's

39:22 . No, it's not a zillion . It is. It's a common

39:28 . It's called me. Okay. that's one you have to remember

39:41 You mean? C U M E E mm hmm. Mhm.

39:53 Then you have the left field line , Which is two Benzene rings.

39:59 you used together. Okay. She a double bond here. Double bond

40:07 . Double bond here. W one in the double bond naturally. There's

40:17 other way to name this except Natalie ! So this is normal painting.

40:36 can call this two missile two missile great disability. Yeah, this is

40:55 new painting. So this slide is simply two emphasize this phenomenon. I

41:10 this normal maintain, I call this Hussein call this normal hip pain,

41:17 octane normal no need normal day cane the cane though they came try the

41:25 cetera, decade to decade. Pizza cetera. Right not a decade.

41:33 I changed the nomenclature now I've been to put it in a casino.

41:38 where the difficulty stems in. yeah. And then you know,

41:52 becomes quite complicated. Yeah. Okay these compounds have different carbon numbers and

42:06 different boiling points. The number of image that I can make out of

42:13 carbon rings. Carbon atoms in a . Yeah. Three ice climbers.

42:20 , I simmers simmers. I don't for you to remember any of

42:28 Just that you can have very different and you can remember the names of

42:34 structures if you know how to do nature. Yeah. See how it

42:52 become so complicated. 100 carbon Boiling Point is 715 and this is

43:02 number of prisoners that you can make of bed number of carbon atoms.

43:10 why organic chemistry becomes so complete. it. Yeah, When I have

43:18 pieces. Uh seven carbon atoms in structure. I don't mean to say

43:28 have seven carbon atoms clearing. necessarily there will be six carbon atoms

43:34 the ring with a branch. So have 16 Al Que Nice Numbers.

43:42 normal elkin, NC 17 8 Isil . I see seven. You have

43:49 cyclo al canes. If you want spend time we can draw them.

43:54 I don't think we want to I think so. 700 Gardens in

44:04 Gulf of Mexico Crude. You can There is one compound called Normalcy seven

44:11 compounds called I C C 77 compound Sai club C seven. If you

44:18 time, if you can try to this, when you go home

44:23 try to do some of those Okay guys, The C7's can be

44:40 or they can be one of them be an aromatic compounds When you have

44:47 drink. Yeah, you call this told you me. Mhm. He

45:02 16 Lk nice summers and one aromatic . Um, so this is normal

45:24 can be roll like this commercial group exile group one with a group and

45:37 , so this is normal empty. can somebody draw me the 2,

45:43 diamonds. Help maintain who's going to and get up to the board.

45:48 reached some of that stuff and put me The three is all contained or

45:55 go with the 22 diamonds all Who's going to do that. Mm

46:01 , 2 dimensional 20. Can I some lady here? Yeah. Please

46:10 attention to that. It is what have anyone. So what is that

46:46 maintain? You see why this is pain tain. See why this is

46:52 from the painting, see the pentagon then two missiles right in position to

47:02 to to die miso And the NK right. No, see why

47:17 compound is called the way it's called to to die missile. Right,

47:30 , you know, did I miss ? But it's a c fight with

47:41 methods. So the root is a right? with two methods in position

47:52 two. Give me a nice summer that. A compound can you

48:01 And I sort of that compact? Right. Look at the structure.

48:17 many other ways you can make different ? Why not have a method group

48:25 position two and the method group in three. Why not? Yeah,

48:39 onto the metal groups to another carbon up and it really do another structure

48:51 the method you're going to say We just finished drawing the things.

49:27 , right. The position was Mm hmm. Work is work peace

49:43 you feel very, just like the that Thanks. Yeah. Yeah.

49:51 . So Uh huh. It's very proposition. Uh huh. Mhm

50:15 Yes. So most excellent tree Yeah. Okay. African american.

51:50 . Thank you. Uh huh. to see that. Yeah.

52:47 Yes. Oh yeah. Oh yeah . She's great. We may not

53:38 seen you can see that the pain I do in decision freely.

54:02 To see that fundamental, see how ways I was able to treat

54:21 Humans are really green acres. I you to remember that and know how

54:29 do that. Yes. Yeah. longest jane that becomes my room.

55:03 it's fine. Covenants 17 6 covenants my method. Two groups. That's

55:15 vaccine structure. Okay. Yeah. fire to to see china to be

55:32 and somebody throw that structure at us . Can somebody use components 2 to

55:46 . Mhm Yeah. Very simple beauty right, absolute. He gains with

56:15 carbon ethics that hydrogen is implicit because don't have it on the second

57:14 It's implicit. Right, So so this compound and then what's the

57:26 And then you have two three. trying E. G. Yeah.

57:50 . Okay, so Too much. like saying clear criminal like same clear

57:56 as contained clear 2, 3 diamond contain clear 2 4 times have been

58:06 33 dimensional thinking clear 2 to Trying to find beauty to make science

58:16 one position and the not admit side the other position. He the nomenclature

58:24 very simple really. And this may an exam. I don't know what

58:32 but and we have a question related this kind of situation. The

58:39 I think No, I have Okay guys, is this is this

58:50 clear in the nomenclature guys. And of course they have the concentrations

59:02 it's not unique. It just happens be this particular compound distribution in the

59:12 of Mexico. But you can imagine it can be different in terms of

59:19 exact concentrations of all these different customers think. Okay, so there were

59:37 hmm um one normal para film Brandished benefits. Right. And so

60:08 , when normal Kane ate ice oil and seven cycling Elkins, seven C

60:21 plus one aromatic structure. So that's Benzene in the metal group would have

60:31 you in. So this is what mean. So C7s can be one

60:38 eight ISIS seven cy clicks and all . Any questions on this concept so

60:53 in the nomenclature, everybody knows why are called what they're called. two

61:14 . Three missile explain that's clear. , six last one, six plus

61:27 position two position 3 five plus It sounds to to die missile

61:41 That's clear. Right. two for is help maintain. Do I need

61:47 to come up to the board and it? You can see why all

61:50 are named the way they are. can see why this is called

61:55 I'll be taped 2 - three. missile beauty. Okay, so seven

62:05 numbered molecule can be in all these all my summers of each other effort

62:16 properties they're different in structure. So yeah, you see a peculiarity

62:57 reality here. You see why these are named the way they are a

63:06 my missile strike lexi is all set maintain 1 1 Diamond side sacrament

63:21 What's the difference between the the trains assists time design. Cyclops maintains 1

63:37 dimensional security. Yeah. And since diamonds on second the big game.

63:52 . This trends trends on this time one plane the other meantime in a

64:01 place they're different. The properties are to be different because they got commentary

64:08 going to become different once the geometry different, their boiling points are going

64:13 be different. Okay, this Trends Key Trends. Yeah. Okay.

64:27 there is a want to damage cell painting. There is a different one

64:35 the middle section, C, Cis trans. Or I can have 1

64:40 diamonds elephantine this interest. Yeah. when you go home practice naming these

64:57 . You see why the names have be different or you'll see why given

65:03 name. This is her name. trends simply by the geometry of the

65:14 . If the two missiles are like the boiling point is going to be

65:19 from the born in point of the the was to missile in this

65:25 Which do you think has a higher point this compound or this compound The

65:35 that's gonna have higher boiling point is he's drawing this way. Who's they

65:42 better than this way? They don't as well boiling point of this is

65:50 from the political today because they pack . Same carbon numbers did it?

65:58 but they had differently and so they to be named differently and their properties

66:03 going to be different the least of is the boiling true. And you

66:09 why the body which is going to different because they back differently. Is

66:16 clear guys me? Mhm. Yes . Oh lunchtime. Oh I guess

66:32 not that hungry. Yeah. Can we leave everything the way it

66:37
