We introduced a new expression for the Hildebrand solubility parameters by means of conceptual DFT calculations. Our results reveal that the cohesive energy density of the HSPs can be replaced by an electrophilicity density. The corresponding expressions are compared to experimental HSP values for a broad range of solvents. Our results reveal a good agreement between the calculated and the experimental HSP values. Slighter deviations can only be observed for solvents with moderate or strong hydrogen bonds and high dipole moments D > 5 Debye. Noteworthy, these deviations were expected as the original HSP approach is restricted to aprotic and apolar species. In addition, our results reveal that higher order and perturbation contributions only slightly improve the accuracy of predictions. As already discussed, such approaches come with the cost of more free fitting parameters in combination with complex expressions. Hence, even more sophisticated approaches are not able to accurately describe hydrogen bonding effects such that our simple conceptual DFT approach is sufficient for practical purposes.
