Bonding
AQA Content
explain the existence of these forces between familiar and unfamiliar molecules
explain how melting and boiling points are influenced by these intermolecular forces.
Specification Notes
Forces between molecules:
permanent dipole–dipole forces
induced dipole–dipole (van der Waals, dispersion, London) forces
hydrogen bonding.
The melting and boiling points of molecular substances are influenced by the strength of these intermolecular forces.
The importance of hydrogen bonding in the low density of ice and the anomalous boiling points of compounds.
