• Non-polar molecules use London dispersion attraction
• Polar molecules use dipole-dipole attraction
• Hydrogen with nitrogen, oxygen, fluorine uses hydrogen bonds
  • Hydrogen bonds determine solubility in water
• By strength: ion-dipole, hydrogen, dipole-dipole, LDF
  • LDFs can be stronger than other bonds with many electrons
• Boiling point is affected by the attraction strength
• Shape and size play role due to affecting contact points
• Strength of LDFs depend on the number of electrons
