Intermolecular Forces – AP Chemistry

1. Which IMF is present in ALL molecules?

Hydrogen bonding Dipole-dipole London dispersion Ion-dipole

2. Water has an unusually high boiling point (100°C) mainly because of:

High molecular weight London dispersion forces Hydrogen bonding Ionic bonds

3. CH₄ has a lower boiling point than C₄H₁₀ because:

CH₄ has hydrogen bonds CH₄ has weaker London forces (lower MW) C₄H₁₀ is nonpolar CH₄ is ionic
