10) where Acav is a proportionality coefficient, VB is the molar volume of the solute B, and δA2 is the cohesive energy density of the solvent A. Thus, in a series of solvents for a given solute, the positive contribution of cavity formation to ∆solnG°B increases with the squares of the solubility parameters of the solvents. For a series of solutes and a given solvent, it increases with the molar volumes of the solutes. It is more difficult to estimate the contribution from the dispersion forces to the solute–solvent interactions.

Their polarity is manifested by a permanent electric dipole in their molecules, since their atoms have differing electronegativities. Oxygen and nitrogen atoms, for instance, generally confer such dipolarity on a molecule, acting as the negative pole relative to carbon or hydrogen atoms bonded to them. 54 D for hexamethyl phosphoric triamide [1,2]. 83 D. 1. , µ = 0) are called nonpolar. 31 D). 0 0. 09 ϳ0 ϳ0 ϳ0 0. 0. 37 0. 15 0. 50 0. 3 Source: Refs. 1 and 2. a Water miscible. b At 25°C. , in the gaseous phase or dilute solution in an inert solvent.
