Can someone please explain to my high/low B.P, M.P and Freezing pt? I'm getting really confused between all three of them. I need to learn them for the conceptual question for Gen-chem. I also tried looking for Chads lect on them and I could't find it.
 
your question's a little vague. are you asking about trends or colligative properties or the price of rice in china?
 
All 3! Trends, C.P and the price of rice. Lol...

For example if they show me 5 compounds and ask me to rank them in highest M.P or B.P or F.P or the other way around.

First off, to make things a little easier, the melting point has the same value as the freezing point.
Second, these are all colligative properties, meaning they are affected by the number of particles in solution rather than the identity of the particles, so when asked which compound has the highest b.p. in solution, you look for the compound that dissociates into the most particles (since boiling point is elevated when you increase the number of particles). Freezing point/melting point is the opposite, and decreases with an increased number of particles
