And this question we're comparing the effect of inter molecular forces on the operation cooperation basis. Uh huh. Molecular wasn't remember vapor pressure defines the boiling point because if liquid only boils when it's flip operation is the quality of the atmospheric pressure surrounding that liquid. So for us to determine the effect of intermodal forces on the operation, it means if the inter molecular forces are with we forces call to high vapor pressure because an increase, this is a decrease in the strength of course is equals an increase in the ease of evaporation. And if a liquid is easily evaporated, it means there is a higher the cooperation. So moving on this is basically what we'll be looking at. We look at the strength of the inter molecular forces that are prevailing. The stronger the force, the lower the rate of evaporation means the lower difficult operation. So moving in the first set mm we've been given B I C L bri and we are going when we are looking at this, these are non polar compounds, many polar compounds. As a result, the inter molecular forces that are dominant here, are there decision faucet. So for both compounds dominant, inter molecular forces at the dissipation forces. And we know that what then differential is strength of the molecular forces of the inter molecular forces. The size Oh, molecules yeah. Higher the science or the bigger the science equal to the higher the strength. Oh, the forces. So when we look at these two, we can tell that B I. Pr A. Three, you ca done B I see all going. So it is easier, it is much easier to evaporate BICL three than it is to evaporate B I Pr happening as a result, B A C opening is called higher the preparation BSL three has got here. I have a question then be a happy opening. So just to go through that again briefly because this is the same principle that we're going to be using. But the remaining molecules assets, we look at the inter molecular forces that I had to play for this one. We have been given the A. C. L. Three and P. A. We are doing. And both of these are non polar compounds and for non polar compounds, the most dominant inter molecular force at the dispersion forces. So they are at papa they are equal when it comes to the dominant inter molecular forces. But what then differentiates them is the size of the molecules. P A P R three has got bigger molecules than P I C will bring. As a result, P A P R three has got stronger participation forces, strong participation forces. If it has got strong anticipation forces, it means it is more difficult to evaporate it as a result to have oppression is lower. For PHP are trying so when we are looking at this Be a SEAL three has got a higher population because it is easy to evaporated. And why is it easier to evaporate? It is because the strength of the test patient forces. Uh huh. Weaker than those of B. I. Pr. So moving on comparing C. O. And the bottom. When we are looking at this we know that ceo is non polar, man, Paula. No ceo is polar. This is a polar compound. C. O. Is polar. As a result I would expect it we have dip alta typo was it? These are the dominant inter molecular forces. Then you also look at it the auto when they are looking into the ocean comparing it to see or to see or to to comparing it to see all. we can tell that the dissipation forces that are in C. O. Or the table to table forces that are in C. O. Are weaker than the forces in coton. As a result, it is much easier to evaporate ceo than it is to evaporate CO2. As a result we've got higher vapor pressure of ceo. Yeah, more than one comparing and to end and all. And true is nan Paula. It is a non polar compound. Therefore the most dominant inter molecular forces are dispersion forces and or on the other hand is polar. Therefore the most dominant into molecular forces are departure. Hey paul forces and when we look at the strength of these forces, we can tell that dissipation forces are weaker than the day poor today paul. What as a result it is much easier to break the inter molecular forces in nitrogen than in in so it is much easier to vaporize into done and all. As a result we've got a higher population into them and all moving on to protein. We've got meet al format middle format again I said to that's it. So these are very interesting compounds because these two have the same formula and formula and on the same side. Bye. What's interesting about this is ascetic acid forms hydrogen boy. But little format cannot. So we can just assume that the dominant inter molecular forces mental form and uh decision. What's it? So when we compare the strength of the inter molecular forces that I had to play within these two molecules or these two compounds, we can tell that these hydrogen bonds are stronger than the inter molecular forces found in middle from it. As a result it is easier to evaporate or to vaporize middle formatted energies to reprise ascetic, because the inter molecular forces at play are weaker in middle format than they are in a setting us. As a result, the rate of evaporation of middle format is higher than that of ascetic acid. Hence the population middle format is higher than that of ascetic acid.
