The first compound is hexane.
00:03
We can write it in an abbreviated form, c6h14, and it wants to know what its strongest intermolecular force is.
00:14
The strongest is going to be dispersion force.
00:22
Although there is some bond polarity created between the carbon and hydrogen bonds, due to the many carbon -hydrogen bonds and their orientation, the molecule is essentially nonpolar.
00:34
The difference in electronegativity is only 0 .4 anyway, and 0 .4 or less corresponds to a nonpolar molecule.
00:47
Then it wants to know about br2.
00:51
Its strongest intermolecular force is also going to be dispersion, because there's no electronegativity difference between the two bromines.
01:02
Therefore, it also is a nonpolar molecule.
01:09
So are they miscible? miscible means that they can mix together in all proportions.
01:15
I'm not quite sure about that, but they definitely are soluble in each other because according to the principle of like dissolves like, the hexane will dissolve the bromine because they're both nonpolar.
01:29
So the answer is, we'll say yes, they are miscible because they are are both nonpolar.
01:41
Then for the next question, it wants to know about ch3oh...
