Provide a mechanism that explains formation of the following products. Indude all intermediates, formal charges, and arrows showing electron flow.
Everyone said you were doing Chapter eleven problem eighteen, and this from asked us using these followed Regent's How We Prepare There's final product here. Show all your agents and curved barrel curly arrow mechanisms to show the movement of electrons. So this is kind of like a retro synthesis problem, but were given all the information we need. We just need to show the mechanisms. So I didn't find the products. We didn't break up the products into different components off that we're allowed to start with. So obviously the little bond is most likely going to originate from the triple bar. So we know that double bond. It's from the triple Bond. We see that we have kind of this one, two, three, four, five carbon structure or substitute int on this side of the Taliban of double bond on the right side of the Dole bond. And we see that we're starting off with one, two, three, four five carbon alcohol. Hale I, which is actually to be actors, are electrified all somehow so we know that eventually we need to make this kick off the roaming to form this entire side of our monk. You hear So we know that this response to this entire section here leaving us these two carbons with this to carbon alcohol a light over here. So obviously combining these two Alka Haley's together is your central al kind. So let's use the AL kind to first ad one of these situations and arbitrarily all just choose this green one here So I'll use my own kind and I need to make this Al Qaeda to nuclear fall. So Khun Nuclear physically attackers carbon and kick off the bro Ming and we know that obviously this is going to be the nuclear file. Not this, because this has a leaving groupon also your life Your father is going to be the the molecule that has your leaving Groupon. So we know that in previous examples, if I add something like sodium height, I dried, I don't know tracked one of these protons making carp and ion, so we know that will fully drawer mechanism the high driver abstract these protons making bond, we make a buying break a bond. So those two electrons in the signal bond will go on to the carbon nucleus has shown here I don't form Hai Jing gas, which will just dissipate from the reaction vessel. And now that's that one step too. If I add my regent, I know that the two electrons on the carbon being very reactive and actors nickel fall and doing Ehsan too concerned one step Mac to kick off our leading group and form this intermediate So country carbons we have one, two, three, four, five. Now we're left with this, plus a broad mind and I don't So now we know that we need to somehow form Sorry, the product that she is a triple bond not available on Syria. Miss Read that so it actually makes it easier for us. So this is very good. So we don't have to use any poisoned catalyst to reduce a triple bond to a double bond, but not any further. So I'm sure we'LL be talking later chapters, But if you use some sort of Lin Lear's catalyst, it's called will be able to reduce Al Qaeda and Al came without going fully down to an Al came. So that's what I was going to suggest. But because the product has all kinds makes our lives easier. Now we need to make this side of the aisle kind and nuke will fall again. So we could nuclear physically attack this electro files. So once again, I'm soon his same re agents number one being sodium hydride number two being my alcohol. Hey, lied saying hi. Driving each minus gonna pick up that proton making bond, You make a bond break a bonds. Those two electrons are going to go onto the carbon nucleus. Two former carbine ion. And now carbon is not very active. Very election on riches. And that was a nickel foul to go through an s and two concerned one step mechanism one hundred eighty degree back set closer like a tuft to form. Now, what is going to be our final product? Plus, don't forget all years side regions, you each to gas. You won't have any B r sorting, bro. Might as assault. Being formed here is well and we're end off. We're left with our final products
Yes. Let's draw a stepwise detailed mechanism for the following reaction. So we'll start here reactant. Yeah. And for step number one and remove a bro Ming Adam, plus charge. Then we'll have each O c h two ch three. This would come in here, and we can have two cases here. Um, over here, in case number two, we can have above the plane attack. And that would look so this here we have six black seen ring. We have oh, ch two ch three positive church each. And this would come in here and then we'd have step number three minus c each Plus, this would yield Bring oh ch two ch three. And this would be plus each PR or this could come over here. And step number two would be below the plane attack. This would yields Oh, ch two ch three plus hydrogen. This would come in here Step three minus h plus. And you would have structure here. Oh, ch two ch three also plus HBR. So here's our stepwise mechanism that shows the formation of the products and the two products that are formed. Uh,
Question journey wasn't trendy. Requires to write a mechanic. May can you sum for this reaction? So we have been young creation and another as the Know what? Your Grammy can use them. You had a mechanism for Britney on the original Nestor and question for thing. So we've looked at the cuts from 14. And the view you want. Oh, my master in this subject. So this will tow this cabin and reduce this squad. And they said, And you have someone? Yes, you. You. So this will go. But this I and you go this and the ring will open. All right? No, you got this one. Did you continue to another Britney variation? This, Tom, this will again this fall. So you get the new combat and this time you got do and you need to goto acidic environment. Was he? And this will There will be spawn. And this will go through this. I knew that. This that this one And you got that at this point. So we had new gumbo in this. Your final product. The more this so this month
Now here. The question number 13 is draw the contributing structure indicated by the curved arrows. Be certain to show all valence electrons and all charges. Okay, so in this case uh the carbon arrows are showing that the electron pairs are shifting from one place to another. And we have to take care of all the valence electrons and charges while making the contributing structure. So here the first thing is that uh in a structure I think 01 Uh car is missing and that is when the when this electron pair is shifting from here to hear yeah, looking to this, we can make the structure contributing structure and taking care of all the valence electrons. So it should be instructors should be all the position of the atom we are making first by putting the single bond between them. After that, this double bond is not here and it is shifted to oxygen. So this electron pair we are making here which is here and with these charges also coming over here and this electron pair is shifting and forming the ball between carbon and oxygen. And no more charge left over here. And we have only to little fanfare at this oxygen. So with this this a structure is over now. Come to the B structure in the restructure hydrogen, carbon, oxygen and self season. So looking to electronic configuration, uh we are writing first place of the all atoms without disturbing their position and single bond. So this electron is no more here and forming double bond between carbon and oxygen. So we are making the double bond here and after that too little in pairs are left. So we are writing to electron pairs and the electronic shifted from here. So negative charge will not be there. And after that here only one single bodies left and this electron there is already there and one more electron pair is coming over here. And with this one charge is developed over here. So this should be the B structure contributing structure. And now come to seats see contributing a structure should be seen as we are making for the A. N. B. Just first right. All the atom positions. Ch three must be here with single bond with single bond here on oxygen. With one more single bond here with oxygen. And after that one CH 3 must be here. After that. Look at the arrow here, one electron is not shifted. Other electron pair is forming the bond between carbon and oxygen. So it is here and here this electron pair is forming the we shifted to this oxygen. And with this some charge must be here. So negative charge we can draw here and that is how uh this negative charge. And here it should be one positive charge because electronic shifted from here and plus minus total charge will be zero and here. Also, there is no charge over the structure. So I think this should be the structure. Look for the foresee as contributing structure.
