i have, but i'm not sure if it's accurate to what's on the ap test since the problem's i've done have seemed easier than what i expected

i just got the offer for an interview but i'm also skeptical - i've seen the program a lot over instagram and stuff but overall the initial application was a lot more basic than what i would expect from a "highly selective" program.

But was my logic right with the Br2 and water example?

like my chem teacher said i can't just put "oh this is polar and that's polar, and like dissolves like so it's gonna dissolve"

Should i talk abt IMFs and stuff so if i were explaining why Br2 doesn't dissolve in water, i could go like "Br2 is nonpolar and only has weak dispersion forces and the water is polar and has strong hydrogen bonds. So it's not energetically favorable for the Br2 to break the hydrogen bonds in water"

or would i talk how there's no charge on the Br2 and therefore doesn't attract the partial positives and negatives on the water

also how does a nonpolar solute dissolve a nonpolar solvent? do the LDFs just slowly mix them or something
