Here in question Number 58. Reaction of HBR with three metal cyclo magazine. It's a mixture off four products mixture of food products, these air to products of food products air here season Trance one broom Oh three Mittal Cyclo magazine and Cease and chance one promo to Mittal Cyclo magazine. The analog ALS reaction off HPR with three promo cyclo magazine is trance want toe dive promo cyclo had seen as the sole product brought the structures of the possible intermediate years and then explain why only a single product is formed in the reaction off HBR with three bruma cyclo vaccine Now here one by one we are trying to solve that. How in case off faster it is, uh, giving CIS and trans for ice Mercy on. And where is in the second case? Only one i summer. So first is when three retail psych logs in is taken Mhm. Here it is when we tell group here Mitchell Group here and double Bond is here. No, When it is treated with HBR, electrons are taken by H plus I am so here it is h plus and we are minds by this. What happens? We are getting a carbon imma Positive charge appears here and we turned group is here now. Beer minuses left This beer minus can attic from Evo or below because the carbon in iron is plainer molecule so it can attack from this site or it can a take from behind. And when it is so by this we should get the product that is the second one Bravo is coming here and cream it'll component will be here and because off the chances off attic off br minus and from both the side we're getting CIS and trans I somewhere off this so two products are found now, in the second case, when the scene l king is taken cyclo eggs e and a third position we tell group is present Then the difference is only when the electrons off by electrons are given toe edge The sign So here these electrons are given toe edge present such a week so that we're getting the carbon iam and at the seconds so carbon, in my information is taking place like the second place by these and want to charge appears here and here we are minus and can a take from Buddha set so it can take below or it can attic from ever. Both decide it is possible. And because of that, we're getting the product. That product is CIS and trans both but beer is at the second edition. So it should be We are here and you tell group is as such does not disturb. And here again, we're getting there CIS and Trans boat. So this is how in the first case, we're getting boot And for a summer self font, Where is what happens here, Here when the starting component ease three broom Oh, we are here and double bond is here. Then the same reaction that is reaction with H b r Here again, edge is plus and V R is negative. No, Due to formation of this car book a time at the second position. We're getting the car book a time. Make this beer is not losing the position. Imagine and wants to charge a fee asleep by this. What happens? This is not the intermediate. It is just for a fraction off. Second, the structure will be there, but immediately electrons off, bro mean is given to this car book. It on because it is very close. And by this we're getting the structure intermediate. That is cyclo eggs and dream. And at the same time, when morning is formed, the beer beer positive appears here and one is at is to this and second is uncertain as to this. So this cyclo bro ammonium iron is formed. This restricts the attic of beer Magnussen from the same site. And because of that, when the remaining beer is a ticking this beer minus, he's attacking a girl. Intermediate The cycle iccpr ammonium iron than what happens. Beer is very big molecule. So now the if this beer is coming up, then the attic can take place from down from the same side because of the larger structure Hysteric hindrance. It cannot take place from both the side from the same side. And we're getting a compound that is one beard about the plane and another beer below the so trans eyes. Summer for mission is only possible. And suppose this beer minus, which is left here, is coming from below. And this be our is able. And with this we're getting this component. So that is how we can explain that how this compound formation is taking place. And here we're getting only trances him here. We're getting the transition because the air is Parky group and due to steady kingdoms, attack can take this from the other side only.
