What to Focus On

  • Intermolecular forces are weaker than chemical bonds but crucial for liquid state.
  • Ion-dipole forces are important in dissolving ionic compounds in water.
  • Dipole-dipole forces exist in polar molecules.

  • Liquids have fixed volume but variable shape.
  • They are almost incompressible due to close molecular packing.
  • Diffusion in liquids is slower than in gases.

  • Vapour pressure is the pressure of vapour in equilibrium with its liquid.
  • It increases with temperature.
  • Boiling occurs when vapour pressure = atmospheric pressure.

Common Mistakes to Avoid

Evaporation only happens when the liquid is hot or boiling.

Boiling point is the same everywhere for a given liquid.

Vapour pressure increases with the amount of liquid in a closed container.

Memory Tips

Intermolecular forces in liquids: Ion-Dipole, Dipole-Dipole, Dipole-Induced Dipole, London Dispersion, Hydrogen Bonding

Evaporation occurs at surface, boiling occurs throughout the liquid

Surface tension causes spherical drops

Cohesive forces vs Adhesive forces
