Why Do CH3OH, CH3Cl, and CH3Br Have Different Boiling Points?

[Paulo2014]

The boiling points of three compounds are: CH3OH, 65C; CH3Cl, –24C; CH3Br, 4C

Discuss the relative strengths of the intermolecular forces in liquid samples of these three compounds.

what should I include in my discussion?

 

[Borek]

Explanation how boiling points depend on the intermolecular forces?
