Hi, everyone. So, in order to tackle this question Okay, we'll see in first 19th. Yeah. So this would be for such to TV. Is there? Our substrate is their age plus skin minus. So this undergo a cento mechanism in present self acetone as a sole went mitigated ground. No, not builds. Excuse us three. Yeah, it's man candidates. Sigh made. What is mechanism? Yeah, mechanism of this reaction. Oh, so in orderto see, the mechanism will force draw the sub strict. Hey, so in this case, you know, reaction is a cento So nuclear fanatics from the side opposing toe grow mean So what you get is in other words, a backside attack of the nuclear fire takes place by excited accompanied Blute fin takes place so it undergo the same to reaction They excite attack a bank off CN minus to reach roaming departs, roaming be pops. The arts but blow mean is not attached to the Kyrill center domain. It is not attached to the Tyrol center. My parents to the viral center, Cardinals center. Therefore, stereo kmsp Uh huh is not taken into account is not bacon into account. Oh, than being mhm. So you can go like this, That is well, I think Lane indicates Brahman is coming towards the absurd. What are coming about the plane? Less loneliness. See? Extreme. Uh, this also undergo ascend toe making itself okay. So in this case, since the prominence attached to the corral carbon, there is an inversion of configuration takes place. So now will rate the mechanism. No, but it's mechanism. Mexican mechanism is step by step description of any chemical reaction. So, no, in this case, this liberal me then this sense Hey, division. So we talk, Cillian, you too. Thanks. On the backside. Mhm to reach Rome. India bars eso What That is? Yeah, so they percent emerging off configuration takes place. Takes place. You do back Syratech in case also, that is a way out of Magnus. So yes, and do my can is, um my kidney something since bro mean is that Kyrill center Kyrill carbon 100% inversion off configuration takes place. Takes place. Do you look like Syratech? Yeah, a tank off. Oh, minus. Yes. That really moto the See? Okay. See, part of the question that kids here is Yeah, Then C h two heads to CS three love? Yes. Three or age, right? This proceed if I a s n one mechanism. So yeah, l a gate tubular. Yeah. One is with a retention in configuration on one with inversion in computation. So this is people sent. You can say, since it involved both retention and now inversion, we can label it as a civilization. So I have a civilization takes place All this mechanism making yourself so you know, be our land. C h two c h two. She is so severe. Become a bone, becomes a polar and send one mechanism. Andi, Therefore, Brahman first gets departed and still gate a Carboni in Miami playing this Now you know there are two possibilities. My pills. I don't need clear file. Yes, to me or h it. Also in writing this Yes. Off page? No, you know, nuclear fine. In this case, you can say attack from the same site to each blooming departs. So it is a French side attack are it? May attack from the sale opposite to the Roman item. So you can say this is back. Syratech, make Sarah Tank. Yeah. So once it attacked from the French side, what do you get delegate are interesting. Positive charge. And this C H two said stuff ch three nine. This erosion loses it. That is, it forms ageless. So Okay. Oh, ch three men. Yeah. C h two c h two ch three No, in back side A deck that this So this is actually a retention in configuration. A retention in configuration Nos my back Saturday. Okay, you know. Okay, so this also yesterday approaches from the back side should not be a positive chance. So this proton undergo loss on real gate. Okay, Inversion of configuration in watership off compilation and therefore s someone mechanism. This reaction follows. And one mechanism at banks off methanol takes place from front and back side bank side. And this I see magician doctor takes place. Then we will go for a D reaction. Yeah. Okay, so no, in our edge, then. See? So we do a child, man, it is I. Then this is no ch three less CS three ch this creation process via and sent to making yourself. So you get 20% in virginal corporation like these secrets five than edge then ch three. They say it's all seasonable. Von does Yes. Yeah. Now, let us study making is, um, making some of the reaction so possible will draw the substrate there. These carbon, then C two h file, then? Yes, it's what he's saying. Ch three I So you know C S d c h. She has three, then syllable Wando. Oh, age. So, you know, wintertime from back side to which during the pulse goods are indeed parts. So you gained. See bridge for you bank yet? Yeah. Search tree. Oh, Seasonable Wando ch three. Yeah. So this undergo deeper donation and still Gates, you could not do it. Nay percent in original compilation CS three oh, school CS, three 100% in Russian. So does reaction process. So I ascend to mechanism back. Sarah, take off. Yeah, Nuclear file takes place, resulting in 100% inversion of computers on a few duration. Then we'll move. Waas The e e part. There is, uh, esto fund will draw this NPR, right? Yes. So this under will I send to make any ism on and again, huh? Less seed rich for you Arrange. So yeah. In this case, prominence attached. Oh, a viral carbon. And that's why in original contribution takes place. So 100% in words. Now, let us see the mechanism. That is how it takes place. Mechanism? No US PR bank spills. Yeah. Okay. Okay. Plus, you can say C two h U Oh, edge. So this would like bank from this side. It's become in regal. I So what we get is yeah. This than Yeah. Okay. Exact Opposite configuration brigade. The to the ends with Come to this side. What do you say? Oh, seemed to edge for you yet. Plus, so this undergo deep rooted nation. What? Yes. Mhm. Oh, see, Bridge fire. So I sent to reaction. Like anything back side attack, I think Doug and it was said in original computation takes place. Thanks. Place. The next one is yo, Seals, right, CS three less cst CS to wage. Okay, this also undergo I seem to make any ism. So, uh, in this case, uh, Tulio to take care. This is a dinos minus. So till directly from this, So go. Yeah, CS three. Then there is or Cito Ph for you. Yeah, that is 100% inversion takes place, So make any some make any something now, E no. This is. See end 90 s three and then you know this C S E C s to age. Attack takes place from back side. Mhm, Chief. So Oh, ch two ch three. Yeah, it's I had his day. He drew some. So these the general reporter nation for me. What? Yeah, yeah, or ch two c s three. So E therefore, I cento eight underwear cento mechanism resulting in 200% inversion in the mother ship off computation. Okay, Federation, do you do back serotype? They do backside. A death. Thank you.
