WebBecause Hildebrand (and Scott, and Scatchard) dealt with a theory where the assumptions were not directly applicable to the real world. Hydrogen bonding and polar solvents were not included since the theory was based on the behaviour of hydrocarbon solvents. As such Hildebrand was dealing with abstract entities rather than real-world solvents.
