IB Chemistry SL 3.2.4 Physical property trends
Practise comparing boiling points across organic compounds by relating structure and functional group to intermolecular forces, branching and homologous series trends.
How this is tested
- compare boiling points of alkanes, aldehydes, alcohols and carboxylic acids
- explain rising boiling points in alcohol homologous series by stronger London dispersion forces
- predict lower boiling points for more branched isomers with similar Mr
