Accepted Answer

Hey everyone. So here it says determine if water or hexane is the better solvent for the following salute. So here we have cl two caesium fluoride, Naphtha, Lean and Methanol. Alright, so if we look, water is a polar solvent so it would dissolve best other compounds that are polar. Hexane ends with a nine. That means that it is an al caine and that means that it is a hydrocarbon. That means it's only comprised of carbon and hydrogen and automatically it's non polar. So it would be best to dissolve other things that are non polar. If we look at our choices, we have cl two, we have two chlorine is of the same element. So they share electrons equally. So that would mean that sailed to his non polar and that would mean that it's best solvent would have to be hexane since it is also non polar. Next we have cesium fluoride, sodium fluoride is an ionic compound. It's composed of a metal cat ion in cesium ion and a nonmetal and ion in the form of fluoride ionic compounds are polar. So what would be best in dissolving it? Something else that's polar water. So water would be the best solvent to use for cesium fluoride. Next we have naphthalene which is C 10 H eight. It is a hydrocarbon just like hexane. So it is also non polar. So hexagon would be the best solvent to use for it. Thanks. And then finally we have methanol. Methanol isn't quite a hydrocarbon because it has more than just carbon and hydrogen. It has that oxygen. And more importantly attached to that oxygen is an H. So that would mean that methanol, since it has an age connected to oxygen, it is polar. It has what we call hydrogen bonding as its inter molecular force. Who else has hydrogen bonding as its inter molecular forces, water because water also has hydrogen connected to oxygen. So as a result of this, that would mean methanol is more soluble in water. Alright, so those would be the the order of solvents that could be used on each one of these salutes in order to properly dissolve them.
