Abstract
IN a recent paper1 it was shown that satisfactory explanations of certain aromatic side-chain reaction data are provided by correlation of the alterations in electron density which arise from the various electron displacements (inductive, inductomeric, mesomeric and electromeric) of the substituents with the energy-levels in the initial, transition and final states of the reaction. Such changes, relative to the energy-levels in the unsubstituted parent molecule as a reference standard, were represented by assigning arbitrary numerical values to each polar effect and thus obtaining a quasi-quantitative expression of their resultant effects on the activation energy of the reaction.
