Nonhydrogen bonding organic solvent

In a nonhydrogen bonding organic solvent, one would need a different approach, such as that of Abraham94 ... 

The differences found are comparable with those found in reactions promoted by 0H (H20) ( = 0-3 5000 times) in the gas phase [18]. These results indicate that the reactivity of the gas phase can be approached in the condensed phase by using bulky quaternary onium salts in weakly polar nonhydrogen-bonding organic solvents. 

The case for increased organization in hydrophobic films caused by nonhydrogen-bonding solvents is not as well documented. It is difficult for us to see how benzene can increase the shear modulus of paraffin wax or how tetrahydrofuran can do the same for poly (vinyl chloride). It is possible that we are dealing with a van der Waals bonding in swollen polymers in these cases but much more evidence would be needed before a definite theory can be advanced.
