Arrange the compounds in order of increasing boiling point.

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

    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.
