2.1: Effects of intermolecular forces
Intermolecular forces attract one molecule to the next.
Bonds are not changing or breaking, so this isn't about reactions.
High IMFs lead to:
Low vapor pressure (the liquid wants to stay together rather than evaporate)
Higher melting and boiling points (but not as high as an ionic compound or network covalent solid)
High enthalpies of fusion (melting) and vaporization (always endothermic).
Differences in solubility between polar and non-polar compounds
