We compare several QSPR models for predicting the aqueous solubility of aliphatic alcohols on the basis of physical (structural and electronic) descriptors. Results are compared with previously published data obtained from topological descriptors and with available experimental results. It is noted that there is a remarkable improvement on going from linear models in one variable to the quadratic equations in several variables. Some further possible  extensions are discussed.
