Abstract The ''water-dragging'' effect of various solutes was investigated in biphasic systems made of water and poorly hydrated solvents, namely 6-undecanone, chloroform, and halothane. Like in the di-n-butylether/water system,1 the ''water-dragging'' effect is primarily determined by the H-bond-donor acidity of solutes, while the chemical nature of the organic solvent (provided it is a poorly hydrated one) plays a limited role only. A molecular interpretation is offered whereby the predominant influence of the H-bond-donor acidity of amphiprotic solutes (A) is due to their propensity to form cyclic hydrates of the type A2W and AW2 (W = H2O)
