Organic Chem ?

For immiscible liquids, the total vapor pressure is a sum of the individual vapor pressures of the liquids. Also, the boiling point is lower than that of both liquids. Why?

I thought that boiling point and vapor pressure were directly proportional.

Synthesis of ______ (fill in the blank)

Yeah, so, I was wondering...how in the world do chemists synthesize new compounds such as cubane, which is a cube of carbon and hydrogen atoms. I mean do they just throw a bunch of stuff together and guess what's in there...or do they use X-ray crystallography or something weird or what?

Yeah.
