Pullman); Establishment of a decreasing relation between the
free valence of a carbon atom of a conjugated hydrocarbon and the
potential barrier of a substitution reaction occurring on this
atom; Introduction of the concept of differential density showing
the effect of bonding in molecules; Introduction of the concept of
loge - region of an atom or a molecule in which there is a high
