Abstract The application of cavity theories of solution and linear solvation energy relationships to the interpretation of enthalpy of solution values of tert ‐butyl halides in hydroxylic media, measured at 25 °C and infinite dilution, is deserted, in order to define the intermolecular forces acting between solutes and solvents. It is concluded that solvent dipolarity and solvent HBD acidity effects dominate the solution process. An empirical equation relating the enthalpies of solution with selected properties of both solvents and solutes is proposed. New experimental Δ H s ∞ values for tert ‐butyl iodide in 13 alcohols are reported.
