Alkyl groups can delocalize both the negative and positive charges through ion (charge)-induced dipole interaction with the polarizable alkyl groups. This charge induced polarization of the alkyl group to delocalize the charge is the origin of ‘inductive effect’ of the alkyl groups. The apparent less efficiency in negative charge delocalization compared to positive charge delocalization by a particular alkyl group is attributed to the less polarizing field strength of the anionic charge.
