Abstract
Formulae are derived which express the scales of the inductive substituent constants σI and σ*, the group electronegativities χR, and the polarisability constants P of alkyl groups in terms of base-constants and ‘connectivity characteristics,’ pure numbers the value of which depend only on the number of carbon atoms a group contains and the pattern of their bonding. The formulae are of predictive value in calculating σI, σ*, χR, or P for any alkyl group and in discerning what these scale of measurement have in common and where they differ. It is shown that alkyl σ* is not a artefact as has been claimed, that σI and σ* are linear functions of alkyl group electronegativity, and that P probably has a hyperconjugative element.
