which of the following has the highest boiling point?
i know its e, but why is that the answer? are all questions about boiling points similar? or they they have to do with intermolecular forces? i have a test soon on boiling point problems...
Intermolecular forces play a role in boiling points, for sure, but in this case it's a matter of molecular weight. Notice C2 is the same for all answers with the other molecules being H, F, Cl, Br, I. So the one with the highest molar mass will be the highest boiling point.
