Problem: Arrange the following in order of increasing boiling point:    CsF, CH3Br, CH3OH, CH4A. CH4 < CH3Br < CH3OH < CsFB. CH3OH < CH4 < CH3Br < CsFC. CsF < CH3Br < CH3OH < CH4D. CH4 < CH3OH < CH3Br < CsFE. CH3OH < CH3Br < CsF < CH4

We’re being asked to rank the molecules with increasing boiling point: CsF, CH3Br, CH3OH, CH4


Recall that there are several types of intermolecular forces (IMF):

1. Ion-ion interaction – occurs between two ions. Strongest IMF

2. Hydrogen bonding – occurs in compounds where hydrogen is directly connected to an electronegative element such as N, O, or F; 2nd strongest IMF

3. Dipole-dipole interaction – occurs between two polar covalent compounds; 3rd strongest IMF

4. Dispersion forces – occurs in all compounds and is the primary IMF exhibited by nonpolar compounds; weakest IMF
