Choosing solvents using intermolecular forces

21. understand factors that influence the choice of solvents, including:

i water, to dissolve some ionic compounds, in terms of the hydration of the ions

ii water, to dissolve simple alcohols, in terms of hydrogen bonding

iii water, as a poor solvent for compounds (to include polar molecules such as halogenoalkanes), in terms of inability to form hydrogen bonds

iv non-aqueous solvents, for compounds that have similar intermolecular forces to those in the solvent
