Solids
Liquids Gases
In which of these states are molecules moving?

Higher.
Nonpolar compounds have weaker intermolecular forces holding them together. With stronger forces holding molecules together it takes more energy to break polar compounds.
Polar compounds tend to have higher/lower boiling points than nonpolar compounds. Why?
