Boiling points
Do we need to know certain boiling or melting points of molecules for the final? If so, can someone remind me how we find those?

Re: Boiling points
We don't need to know specifics. All we need to know is the certain rules of boiling points in order to predict if one molecule will have a higher or lower boiling point than another. For instance, you should expect a polar molecule to have a higher boiling point than a nonpolar molecule because of the stronger intermolecular forces (dipole-dipole vs. London forces).

Re: Boiling points
I don't think you would need to know the specific boiling/melting points, but you should know how intermolecular forces impact the boiling or melting point of a molecule. Molecules with stronger intermolecular forces have higher boiling points and melting points because these molecules will be strongly attracted to each other, and high energy will be needed to break these intermolecular forces.

Re: Boiling points
I don't think you would need to memorize anything specific for the boiling point of a molecule besides being able to compare two given temperatures and knowing how that corresponds to it's intermolecular forces.
