Which of the following is moderately soluble both in water and in benzene $\left[\mathrm{C}_{6} \mathrm{H}_{6}(1)\right]$, and why? (a) 1 -butanol, $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{2} \mathrm{CH}_{2} \mathrm{OH} ;$ (b) naphthalene, $\mathrm{C}_{10} \mathrm{H}_{8} ;$ (c) hexane, $\mathrm{C}_{6} \mathrm{H}_{14} ;$ (d) $\mathrm{NaCl}(\mathrm{s})$

So in this problem, we're trying to figure out which one is gonna be soluble in both water H 20 and benzene C six h six. So are right off the bat. We can we know that water is very polar. Um, and that this therefore means it's going to be, uh we're gonna be looking for other polar substances that we can dissolve in water or any ionic compounds, whereas C six h six is non polar because we have that large hydro carbon backbone between carbon and hydrogen. So we're really looking for something that is going to have a polar section and a non polar section right off the bat. We can pretty much tell it it's gonna be this, uh, first compound because we have this long hydrocarbon backbone recieve lots of carbons, and then we know an O age group. The alcohol group is gonna be very, uh, polar. All these other options, this is Ah, hydrocarbon. So it's non polar entirely. This is non Golar entirely as well. And n a C l is an ionic compound, and we know that that's mostly stabilized by the polar interactions from the water, whereas it would not be stabilized in our Benzie. So that's gonna only dissolve in wire

So in this question, we're going to try to understand solid ability. So we want to know which of the following in the pairs would be more soluble. So in the first example, ethanol soluble because it contains a polar ohh boss, ethanol is so Ethan ologists is this and then heck saying um is just going to be the straight chain. Okay, so basically just going to look like that just with the hydrocarbon chain and ethanol has always group. So ethanol is soluble in water because it has a polar, all bonded to age bond, it can undergo hydrogen bonding with water. So as you know, water is going to be Htoo. So you can visualize that we're going to have water here. So the electro negative oxygen is going to take the electrons towards it and then that will make the bond to the h weaker and cause that to have a positive charge. And then the negatively charged oxygen is just going to be able to be attracted to the hydrogen. Um And so this ethanol molecule can undergo hydrogen bonding with the water because it is polar. So actually on the other hand, doesn't have this polar bond, so it cannot undergo the hydrogen bonding. So what that means is basically the ethanol soluble but the heck chain is not. And remember that likes dissolve like so polar solvents dissolve polar solute and non polar solvents dissolve non polar solute. So that is why it would be ethanol. Now the scalability of low molecular weight carbonnel compounds and water is due to the hydrogen bonds that form between the oxygen atom of the Carbonneau group and the hydrogen atoms of water molecules. So what that means is if we have Aldo hide which has this group, it can be soluble because you see that we have a negatively charged oxygen atom and then that can form bonds with the partial positive charge of the hydrogen and that is what will make it soluble. So in this case though we also have this non polar region that causes this to be less soluble. Also the Aldo hide, it is not as soluble as the alcohol because O. Is not bonded directly to the H. In the elder high we have the C. Double bond toe and the H. So in this case we have a rule that Aldo hide with fewer than five seeds are soluble in water, so butin L. Is going to be soluble because it has the shorter non polar region, so it has less of the hydrocarbons, making it non polar and less soluble. Hexagonal has six carbons in carbon change. So it has a larger non polar region. That's what heck smell is not as soluble. So now We look at two different Aldo hides. We have proper now and then we have a longer hydrocarbon chain on an alga hide. So just by looking at this and what we discussed in the previous problem, we know that pro penile is going to be more sellable because of that shorter non polar Carbon chain, which is less than five carbons.

Let's just look out some more properties off. Calm, Oxalic answered, and we're gonna be addressing soul ability again. So recall we had our rules here for our carbon chain. However, now we need to consider different properties in the molecules. So here are example is hen tain on Penton OIC acid. Now that two different molecules that both got five carbons, we can go ahead and draw about 12345 want 2345 So on 2345 Double check your carbon chains. So that is plantain there, that is number one and now, Pennington, OIC acid. Just have the carpet Cilic asset functionality. See, here and now, having this cop oxalic acid functionality will have great to interaction with Walter because you've got your hydrogen. So then that will be able to bond with an oxygen in the love her that would exist. So the car bookselling accident has greater functionality than just paint ain't alone

Hi everyone. So in this question they ask in is each of the following very soluble in water, explain a men's in C success XB Supreme hydroxide. See eternal separation as it did than in each of the following. Very soluble in water explain a lithium nitric big lesson. And I still see a shook sewage 7 10 and be eating like all. So you know celebrity basically. It depends celebrity depends on solid relating depends on nature of component solvent nature of Okay, come following. And yeah, solvent. Okay. Generally for their compounds. Embarks are so level in polar solvents, solvents like water and yeah, alcohol. Yeah. Except generally non polar compounds. Mhm. Yeah. Really? Yeah, non polar compulsives are insoluble in some in solid well yeah. Mhm. And polar solvents but polar solvents like water and co hole like quick water and alcohol etcetera. But Uh huh PSA level in organic solvents. Organic non bullard solvents. Yeah. Mhm. Like benzene. Yeah. Maine sen he tied. No anyway. Hey sam. Mhm. Yeah, chloroform, ex cetera. So right. She west on this uh in brief. Okay. In brief. Like dissolves like mm Right. Like big salts like means polar compounds. They get diesel in polar solvents. A non polar compound against these early non follow salman. No. Yeah. Sorry. Thanks tonight. Here Syrian number. And then you can say come about. Yeah. Then cell ability. Okay. In what? Oh so serial number for late in the former abc. Yeah. Then then. Mhm. Yeah. See. Yeah. Yeah. Mhm. Than be. So a compound is man seen many scene. c. Mhm. Okay. So will the nature of the compound? Yeah. Nature of given compound Given. Mhm. Come out and last. So let me leave. Yeah. In water. What is a solar cell? Mhm. So benzene first compound is there 2nd sodium hydroxide? Is there Oh, sodium hydroxide. Notice any storage and then third eternal. Yeah I cannot. Nine kids. C. two edge by your age then fourth violation. Anticipate. Mhm. Don't miss the yellow as he did nineties. Yes. three c. o. okay that's true. Again. So this sort of one of the thing again. There is a every city. Okay That is you can stay here 4.15 tim. E. Then we then the second part lashed legal pump. So in that AIDS lithium nitric meet yells nitrate. Then I have the second glisten the life saving and H. Two ch two cereals. The next 1010. Mhm. And then the next thing like all. Yeah killing like call. Yeah their deeds. H. O. Ch two Ch 2 or H. No. Now first compound dancing solvency needs non polar. When seniors lawn bowler water is fuller and that's why it is insoluble in what then? Sorry? In Iraq side it is smaller, water is also polar and that so it is so liberal in water. My next eternal when said he needed as they pull up water is a result polar and they say it is son Levon the next operation acidic is Ebola and therefore water is also polar and therefore like business like that. It is soluble in water. What then split to migrate It is a I only compound ionic there is polar and let's try. It is so level in water then listen is a polar molecule, Hollande molecule and therefore son level in water then bring 10. It is non bowler non polar and that's why it is insoluble in water in solid world in water then killing like called okay he did say older Malik. Therefore so liberal in water. Thanks a lot
