Hello. In this problem, we are asked to identify the best Sullivan where sodium format will be most soluble sodium format is a on a compound that will dissociate form its ions we call that ionic compounds are more soluble in a polar Sullivan. So we're trying to identify then among the four solvents that were given. Which then is polar. If we consider a Halloween, then Halloween is made up of just carbon and hydrogen. Halloween has non polar bonds. So it will interact with itself through London dispersion forces. And then if we consider hexane which is C then hexane is also made up of just carbon and hydrogen. So it is also a non polar and will interact with itself through London and dispersion forces. If we consider B then which is dimethyl ether, dimethyl ether then has a polar region and it also has a smaller methyl groups. The polar region will dominate, so that makes them dimethyl ether a polar Sullivan that can engage in depot depot interactions. And then our other potential Sullivan is ethanol, ethanol has a hydroxyl group. And this makes then ethanol polar does have this short hydrocarbon chain but the hydroxyl group will dominate, causing that's an ultimate polar that's an all. Then with the hydroxyl group is capable of hydrogen bonding and dipole dipole interactions so that then increases the clarity of this. That's all relative to the dimethyl ether also dimethyl ether has these groups on the end, which can be bulky and interfere with the ability of us to have dipole dipole interactions. So the best Sullivan then is the one that is a polar Sullivan. So that eliminates A and see those are both non polar. When we consider dimethyl ether versus ethanol. So again, dimethyl ether has these hydrocarbon groups on the end, which are a bit bulky and can interfere then with the dipole dipole interactions with our ions, whereas the hydroxyl group here is unhindered and is capable then of interacting with our ions. And so our best Sullivan 10 is the ethanol. So that would be answer. D Thanks for watching. Hope this help.
