Discuss dispersion forces, how they are formed between atoms and their strength. Examine how the dispersion forces increase between atoms as the atomic radii increase.
Examine dipole-dipole forces. Use examples and sketch the forces between two true dipoles. Elicit why these are stronger than dispersion forces.
Examine hydrogen bond forces. Discuss the formation between hydrogen and high electronegative atoms. Draw examples. Show how and why water is a liquid at STP while methane is a gas. Discuss the boiling point differences being due to water having strong hydrogen bonding and methane having no bonding.
