What is the major product obtained from the reaction of 2 -ethyloxirane with each of the following reagents? a. $0.1 \mathrm{M} \mathrm{HCl}$ b. $\mathrm{CH}_{3} \mathrm{OH} / \mathrm{HCl}$ c. 0.1 M NaOH d. $\mathrm{CH}_{3} \mathrm{OH} / \mathrm{CH}_{3} \mathrm{O}^{-}$

In this problem we have given reaction mechanism Which occurs in two steps and we have to write overall reaction and identify catalyst and reaction intermediate. Mhm mm. Given mechanism is any step one. It's too, or to react with br minus to give. We are all minus and H two and second step mhm Mhm is to go to reacts with BRO- which is formed in step one to give, we are minus plus H two and or two. Here we can observe that The BRO- formed in step one is consumed in step two and that br minus iron consumed. Any step fun is regenerated in step two so first of all, to find overall reaction ID these to step and eliminate the species which occur both side of reaction, most of it on adding we get It's true or two plus br minus Plus H202 plus beer for minus. Yes, we are all minus plus H two. That's bigger minus less age too. And also here we find we are minus and we are all minus president in both sides of the essence will be eliminated. It. I don't know. No, but the most of the time overall Mhm reaction for the given mechanism is two moles of H two or two gift, two moles of H. Tool and one more love auto. Just drop the physics of this is our answer. Four overall reaction. Okay, publicly. Mhm. Now we have to identify catalyst and the accent intermediate as we know that. Mhm. Mhm. A catalyst. This is just is a substance christmas christmas that is paid up a chemical reaction. Yeah. Mhm. What? Mhm. Without consumed? It's just Mhm. Buy it. Mhm Yeah. The catalyst is used up in one step and it. Mhm. To regenerate in Okay, subsequent step. Mhm. Our next step here we are minus iron Is consumed any step one And it regenerates in step two. Therefore. Yeah. Mhm. Mhm BR minus is yes. Mhm. Acting as catalyst. Mhm. Okay. Yeah. Look, look. Yeah. Yeah. Yeah, reaction entered immediate mediates our is pieces produced. Mhm. In one step. Mhm. But used up in next step. Mhm. Yeah. That boy here we are all minus Is produced any step one and it is used up in step two. Therefore, yes, there are reaction intermediates. Mhm. The excellent immediate in this. The accent. Mhm. What? And the the excellent immediate is B R O minus. This is our answer for reaction intermediate. Mhm. Mhm.

And problem, 9.23 were told to start with five that kind and react with the region's given for each part and give the products in part. A. We're reducing the triple bond to a couple bond with hydrogen and delimar Catalyst, and this will give us, uh, double bond and sis position. So now we have trance. We have sis five that keen. Now let's look at Part B and part B. The lithium is going to donate electrons and ammonia is going to donate Proton, and this is how we will reduce this triple bond. Teoh a double bond. The double bond will be in transposition, and a double bond is on carbon five. So now we have Trans, too. If Trans five that came, that came. And just remember that the landmark Alice always gives you assist Double bond and that within ammonia will always give you trans. And now, for part C, we have one equivalent of Romain and we are reacting this with our five deck kind. So this will give us a trans molecule with roaming on each side of the double bond. So here we have Trans 56 Deborah M. 06 checking the king in Part D were reacting five deck kind with more rain and peroxide in the base. This would normally give the non Markov nick off product, but since each side has the same substitution for the carbons, it will not matter whether it's my comic off or non my company cough, and this reaction will only give one product. Because of the location of the triple bond, we are going to have a key tone on carbon five. Now let's look at Part E. Part E. We have the regions that would normally give the McCartney cough product, But again, we're going to get the same product as Part D because of the location of the triple bond. Now, in part F, we're reducing with excess hydrogen and using a palladium catalyst with carbon, Harman normally tends to maximize the surface area in part F. We are going to reduce the triple bond all the way to a single bond and just have decade as our final product. And this is the final answer to this problem

Or something. Which of the foundations will give us a second Iran elbow. We have identified in which of the following compound. We are getting second real cold. Second real do real cold they've got in which direction. So Washington is this but outside and we are in the presence of production as we are. We've got one drama broken one round robin is reacting with the further college minus. Then we will get one property. So it will be one degree more second degree. No problem is reacting with the biggest street In that length of H two words manners. Then we will get one problem. We also incorrect in the sea reaction. We have this one. So that's two s. 04 and that's true. So pipe down will break like this positive, negative. So the question is will attack on this car. So we will get this compound. You broke it Not the compound we have CH two siesta. The function is reacting with us. He has three MGB. So yesterday energy there is a strong base Soc 3- will attack here and bringing a degree. Right? So the women here Cst minus C. S. Three upon his release is we will go this alcohol. So correct. Something only sees the crop tops. Okay, thank you

Hello. Question is vote Yeah there is a reaction sequence. So we have to identify that bad reasons should be used so that we can get correct from the Okay so in the precaution we have when brahma profit. Yeah. And finally we are getting graphical compound. There is a sin compound B. A. That's right. We have to think that in the real world there is only three garden but in the product there is 12345678 eight Carbon. So we have to add five more carbon India broken. Okay I can see. Yeah so painting we will use when tennis world terminal and then we have to use because it helps as a beginning. Yeah. Okay. Okay so this height doesn't build gets animated by a base and it's too much. Then my nestor will come here. This minister will attack on this carbon and it will eliminate. Yeah then we will get. Mhm. Yeah. Okay now this compound is reacting with need a large catalyst that will convert Elkins into society. Mhm. Yeah. Now this company is everything with s. 0. 4 in the present of any S. A. T. Right? So we will get sent by or both. Hydroxy group will add on the double 100 carbon wells in addition. So correct option will be B.
