Answers

Are the following pairs identical, enantiomers, diastereomers, or constitutional isomers?

Starting with part A. We have two is much X enters one here and one here, and that's the same on this compound. And call this the 1st 1 We have our client on a bold wedge in the first compound and also in second compounds. We know that those two of the same configuration and on this asymmetric centre, the metal groups on a bold wedge on this compound in other rooms on the hatched wedge. So you know that configuration of the opposite. So since one configurations the same and one is the opposite used to our diced area MERS for part beef, we have both our chlorine and ERM Ethel on a bold wedge and in some compound, the both in the same spot where both on hashed wedges. So since both of the configurations are opposite, he's Aaron and tumors for Park Si. We have the coin and the siege three on a bold wedge, and in this compound they're both on a hatched wedge. But difference between being see is that the court or the Korean and the stage we have switched positions, which ends up making them happy. Exact same configurations. So these are identical compounds. And for party, we have our five carbon rings and then a chlorine and s Each tree in both compounds were pulled attached on bold wedges. But they have different attachments. The chlorine is on carbon one, and metal is on carbon three. This compound, the Korean son carbon one. And the metal is on carbon too. So these were constitutional, I summers.

So for this question, we were asked whether the following are identical compounds and anti MERS die streamers are constitutional. I simmers, starting with part A. We have be two compounds and we confined their configurations of these metrics centers and the configuration of the first compound in the pair is our and the configuration of the second compound in the Paris also are so since they both have the same configuration Cesaire identical compounds for part B. You can also determine the configurations at these metrics centers. So looking at the first compound of part B, we have our configuration since the group's ranking them, in order of priority go in a counterclockwise direction. But the hydrogen is now on a vertical, so we know that our configuration and I s and it's the same reasoning or the second compound in party. It just also are configuration. So again, since both his conference have the same configurations, they're identical compounds or part C. We have to asymmetric centers. And for the first compound, you configurations of the asymmetric centers are R and R and the configurations of the second the configurations at the electric centers of the second compound our s and s. So since both of the asymmetric centers configurations or opposite, we have any anti MERS for part D. Um, we have different attachments. So thes ch three group in the first compound is in the place of B to carbon Jeanne in the opposite in the second compound. So the metal group and the ethnic group have switched places in their a touch different carbons. So we have different attachments. So therefore we have constitutional. I simmers for E. Um, we have to groups for two compounds and they both have a ring. But the rings don't have the same number of carbons in them. So red, where you can see that they would have attachments any of another pair of constitutional I summers for f we have or compound is a six Furman rang attached to two Koreans in the first compound. The two corns are both Tashaun bold wedges, and in the second compound, one is on a bold wedge and one is on a hatched wedge. So what that tells us is that, um between the 1st 2nd compound, one of these metrics centers, configurations is the same, and one is the opposite so since one has remained the same and one is different, and the different one is the one that went from a bold wedge to a hatched wedge. We know that these air die hysteria MERS for G. We have a compound with a six carbon ring in two quarries. Attash When the first compound, the two Korans, were attached on the same carbon in the second compound, the two chlorine Zahra touched on two different carbons. So we have different attachments, so we have constitutional I summers and lastly, or H. We have a compound with a six carbon ring and two chlorine cash on two different carbons in the first compound, the first chlorine, which is one of the left that is a touched on a hatched wedge. And in the second compound, that same Korean is a tough on a bold wedge to know that that basement rec centers configuration of the opposite and the same for the other asymmetric centre. So since both of them are opposites of each other, we have an anti MERS

So to determine whether each pair is identical on anti murders style hysteria, murders for constitutionalism. We will determine their configurations. So these are Newman projections. And to determine their configurations and try to imagine, um, come in the front and the carbon in the back. But in a format that's kind of like this, um, and you can convert to a perspective formula. Either you had or I couldn't write it down. So for part A, I'll convert it to perspective formula. So this 1st 1 current the front because carbon here in the carbon that back we hear come in the front is touched with no age who put the top also attached to a hydrogen and a CH three current back, which is this carbon on the right. It's attached to to hide regions and the CH three so they can determine e configurations of these metrics center. So the asymmetric centre is this carbon here and not one on the right, since it is attached to hide regions and you know, and doesn't have four unique groups. So the O. H. Has the highest priority, followed by this to carbon chain in the metal group and in last the hydrogen. So if we draw a rose from 1 to 2 in 2 to 3 to go in a clockwise direction. So we know that this has our configuration. When when you do the same thing or the second, um, compound on the right governments in front try here current. The back beyond the right Kerman of the front is attached to a CH three. Ah, hydrogen in a no age current back is attached to a hydrogen, a siege three and another hydrogen kurban on the left will be Race Metrics center. Since it has four UT groups, the weight will have the highest priority, followed by this to carbon chain than our methyl group and then or hydrogen Um, which is on the house to watch. You don't think you change anything, but it was from 1 to 2 and 2 to 3 to go in a counterclockwise direction. So we know that this will have asked configuration. So since these two compounds have opposite configurations, they're an anti MERS. Now we get the same thing for part B. Instead of drawing the perspective formulas, you can try to imagine it in her head so this first carbon is attached to a siege. Three hydrogen and to Herman Gene actually going to drive, The easier we visualize it. So the carbon at the front have been the carbon on the left attached to a siege. Three. Ah, hydrogen. Yeah, I to Herman. Chain carbon on the right is attached to a hydrogen, a bro Mean and Corinne. So this compound has to asymmetric centers since both of the carbons AirTouch to four different groups. So you will determine the configurations of both these metrics centers. This 1st 1 um, this is eyes priority the carbon that it's attached to. According in a rooming. Next is the FL In the method in the hydrogen, hydrogen is already on 1/2 choice. We don't have to change it, so wanted to into three goes in our direction or, ah, clockwise direction. Which means that our configuration so this carbon, this asymmetric centre has our configuration carbon on the right. Romaine will have the highest priority since that is the highest Tomac number. I would buy the chlorine and they appear and then lost the hydrogen. You'll interchange hydrogen with the bro mean, since those party groups were on the hatched wedge go from 1 to 22 to three that goes in a clockwise direction but suggests that it's our configuration. We know that the actual conflict before winter changing, we'll have s configuration. So this carbon has passed configuration for the compound on the right. Kermit, the front will be brought on the left from the back. We on the rate, it's kind of The front is attached to a two carbon chain, the hydrogen una metals. Oops. Current back attached to a chlorine Abreu mean hydrogen. So we have to asymmetric Sanders here again. They sent us on the left. You will have this group of the highest priority in our Ethel that our method in the hydrogen wanted to into three is in a counter clockwise direction. So this carbon has asked configuration criminal right has produced the brewing, followed by the Corinne, then this group and then the hydrogen well interchange, the growing with the hydrogen. Since the hydrogen is the lowest priority and should be on the hatched wedge so wanted to into three, um, has, uh, counter clockwise direction. So we know that the actual configuration before into changing is our So if we look at these two compounds, the one on the left has are in us and on the right has snr and since both of those are opposites of each other, party is also a new teamers.

So fast recovering the general trend that we need to help in order to understand the podcast. So when we had to change to groups of a carol carbon an odd number of times, we will change the configuration of the asymmetric center. So the structures below our Dia stereo Vice Minister, they are non super imposible, non mirror images of one another. So C two and C three change where C one still has the same configuration, so it is numbered one to three. Next, we have two identical structures. So we have the exact same connectivity, the exact same physical chemical properties because all of the atoms abundant in the same way with the same configurations. So next we have constitutional items. They have the same molecular formula but a different connectivity off their atoms. Lastly, the structure below are dire stereo I summers. This is because carbon to configuration changes carbon 134 and five configurations remain the same.
