Abstract
A PRECISE measure of the charge on an atom in a molecule is provided by calculating the number of electrons within a sphere of covalent radius using molecular wavefunctions. The results for alkyl substitution suggest that the simple qualitative ideas of the inductive effect may be less simple than is commonly supposed and that methyl groups are not intrinsic electron donors but rather attracters of charge.
