In this article, we introduce conceptual DFT for the calculation of HSPs. Our approach allows us to replace the cohesive energy densities by straightforward electrophilicity densities computed from simple DFT calculations. The calculated values of the Hildebrand parameters are compared to experimental values for more than 45 solvents, showing good agreement for non-or moderately polar aprotic solvents. The observed deviations for stronger polar and protic solvents define robust limits in which the Hildebrand approach remains valid.
