In this problem, I can die be the extended six fc. Actual plus food and S. Three will give the compound CH two all six and food Plus six H 20. Ch to hold six and four each formed, which is fueled C. H. Two All six and 4 age. You would as an you didn't Eddie and this uptick so according to the option options is correct. Of some seed, correct and set.

Okay, so we have several solutions, and we have to rank then in decreasing prison point. Okay. Um, the important thing about this question is to consider the dissociation pattern and this substance. Okay, so the Friesen point change. Okay, follows this former. It's a constant. Okay, that depends on the substance. It depends on to solvent. There's a negative sign just to remind you that this is going down. So the freezing point goes down as you increase the concentration off the particles. Then you have the morality off the solution. Okay? And there's one extra piece que auction we we can represent as an I that I is used to taken account of dissociation What that means. Well, it really the collective properties, they depend on the number of particles in the solution. Not really. Then the number of molecules just started because molecules, you may have a big molecule, but when you put that in solution, that breaks into smaller particles. Okay, so the number off these smaller particles is what matters. So this I exist to take in account this association. So for example, in this case, I would be three, right? Because this big molecule here or Crystal or whatever is not. He broke into three pieces. Okay, so for each spaces, we have to consider whether or not there would be the association. Okay, so first, let's look at sugar. So the sea, Uh, let's see. Six age, 22. 06 actually, sugar. It's a molecule. Um, and there's no significant dissociation when you put that in water. So it's solid is right. A complete reaction. When he goes through the solution, it won't change the structure. It would just be solve aided by water. So I would be just one because one particle became one particle. Um, the tricky one among the list. And the question is C age three c o. Because this one actually establishes an EC equilibrium. Okay, so once it's dissolved in water, you can he can associates because it's an acid. It's an organic acid, so this hydrogen here can pop out. Okay, Uh, if you don't remember organic chemist er deaths here, C o h. That's an organic acid that's characteristic over an organic acid. Okay, so what can we say about I? We can really say the eyes equals one, because that would say that would be implying that the association here is complete, which is not the case. This association actually is quite small because organic assets are which, in a sense, that their dissociation is to his mo extend. So all we can say is that I is greater than one, but likely it's also smaller than, say to it would never get to being a weak acid. Okay, so let's quickly go through the orders. The under three are actually salt, so it's easier. So I'm going to write this in a simplified way. So, for example, if you have the they saw the salt, the sodium phosphate and it will pretty much completely the associate and to three. So Deion's and a false wait. Okay, so I, in this case, will be or all right for make news in chloride, Same thing that will break into magnesium two plus and to chloride. Okay, so I equals three. And finally we have sodium chloride that would associate into sodium and chloride. So I equals two. Well, so now what we have to do is trying to create a little table and put the I into consideration. So let's say let's see if we can do that. So we have the sugar first we have the organic acid. We have sodium phosphate, magnesium chloride, sodium chloride. Okay, we have the concentration. So point this is in more. That's more the morality. Uh, same thing here. Here we have 0.10. Here we have from 20. Here we have 35. So we have ice. This is one. All we know here is the greater than one hair. It will be for three and to So let's multiply across. So this one 0.15 this one we don't know, but we know it's greater than 0.15. It was certainly be smaller than points through three. Remember? Because I said that it won't get to it won't get to be too. This one will be point for this one will be 10.6. And this one will be 27. So I actually organized that already in order here because now you see that the freezing point would go down in this way because of these values here

The bond order is calculated by the following formula. Oh, number of bonding orbiters minus number of anti bonding orbiters. These are the number of bonding orbiters, bonding orbital's and number of anti bonding orbiters and the bonding orbiters. So according to this formula, we can see that it can assume that is the bond or formula can be assumed the value as positive integral or fractional fractional values and zero values also zero values. Okay, for example, let us take an example of die atomic molecule of helium. So here the molecular orbital electronic congregation for the that technology will will be oneness two sigma minus two sigma and the wounding one is two, then sigma us too Stigma and the Wounding two West. So here when I calculate one order than it is given by half the number of bonding orbiters, the number of bonding electrons. Okay, so these are the number of wanting orbital electrons. Right? We are counting what number of bonding and anti bonding orbital electrons. So here the number of bonding orbital electrons are two and two. So these are four. Similarly in the anti bonding orbital electrons, these are 4, 2 and two. So this will be zero. So here you can see that the bond order is zero. And this is the reason that helium, the atomic molecules do not exist because bond order is zero and such a molecule will be highly unstable. But yes, as you can see that the bond order can be zero. So the assertion given here is correct. Now the reason which is given to us is higher the bond order. higher the bond order. The bond order shorter. The borderland shorter the bond land. So yes, of course this reason statement is also got it shorter. The bond length. This is because higher the warned order more will be more will be full of electrons full of electrons more will be full of electrons more will be the overlapping of orbital's of the bond in world. So that's why I start, the shorter will be the born land shorter will be the born land shorter will be more like now since you're born length is short. So that this makes the born length, the born very strong this mix the bond very strong. Such a strong bond cannot be broken easily and requires very high energy to be broken requires very high energy hi energy to be broken. Hi energy to be broken. And this is the reason why the bond energy will be very high, that's why therefore higher will be the born energy higher will be doc bond energy for breaking down bone bond energies. What bond energy is the energy needed to break the bonds? So since the cool off with electrons is more efficient, that's why the bond line is shorter. The bond length is shorter. That's why the bond is very, very strong since the bond is very, very strong. So the high energy is required to bring the bomb. So the reason statement is also correct. So here, both the statements, both the statements for exertion and reason are correct as a Russian and reason are correct. Listen are correct. But the explanation, the reason given to us is not the correct explanation for the given assertion, but the But doc reason is not the correct explanation, correct explanation for the assertion. Explanation for dark as ocean. So the correct option will be what the correct option will be. Option me. Hence option B is correct. Hands of shin. We is panic.

In this problem, I'm trying the diagram of the U. S. Or foreign to five ash too. So just look at it carefully. Here it is. See you two plus heritage boys to Heritage boys too. Here it is oh H. Two he inherited. As to here it is also edged too. So from this figure we can say that there are pour water which is directly attached today, metal center in the U. S. Of 45 past work so four it's equal to answer or will be the answer of this problem. There are four water molecule directly bonded to do Matter Center in see us of 452.
