WebTable of Content. The inductive effect in a molecule is a change in electron density produced by electron-withdrawing or electron-donating groups in other parts of the molecule, resulting in a permanent dipole in a connection between the two electrons. In contrast to the electromeric effect found in a (pi) bond, it is present in a (sigma) bond.
