different compounds that

dramatic changes in properties are observed when small changes are made to
the functional groups on cations. For example, the solubility of ionic liquids
with alcohols can be increased or decreased by varying the length of alkyl
groups attached to the cation;

whether the solubility increases or decreases
with increasing alkyl chain length, however, depends on the alcohol under
