Abstract
IN a recent memoir 1 E. Hückel has made an interesting attempt to apply modern mathematical and physical conceptions of the electron in valency bonds to an a priori deduction of the distribution of negative electricity in the benzene ring and ultimately to the development of a theory of orientation in aromatic substitutions. The paper has been very favourably received by physicists and also by many physical chemists, who have no doubt assumed that the dénouement in its main outlines is in harmony with the views of organic chemists. This is, however, not the case; so far as we are concerned, we expected conclusions to be reached which are the opposite of those arrived at by Hückel. Where this author postulates an excess of electrons we consider there is a defect, and vice versa.
