Fluoroethane, attractive forces

Both polar compounds ethanol and fluoroethane have higher boiling points than the nonpolar propane We attribute this to a combination of dipole/mduced dipole and dipole-dipole attractive forces that are present m the liquid states of ethanol and fluo roethane but absent m propane... 

The most striking difference, however, is that despite the similarity in their dipole moments, ethanol has a much higher boiling point than fluoroethane. This suggests that the attractive forces in ethanol are unusually strong. They are an example of a special type of...
