Arrange the compounds in order of increasing boiling point.

Question

A) CH4
B)CH3CH3
C) CH3CH2Cl
D) CH3CH2OH

**I know High Intermolecular force = High boiling point!**

My question is if A, B & C are dipole-dipole, and D is hydrogen bonding.. how can i determine from A, B & C which is the highest of those three. Is it the molar mass of each compound?..

Im just stuck on a practice exam and was wondering if they all are the same what is the second thing that can determine the high boiling point.

Thanks

Answer 1

molar mass. The higher the molar mass the higher the boiling point.
CH4 is not polar. Neither is CH3CH3.
Yes. D is highest. CH4 is lowest. Then in order, CH3CH3 is next and chloroethane is next.
