In these reactions, the electron pair moves away from the attacking reagent. Nowadays electromeric effect is often considered along with inductive effect as electron displacement, but can also be applied to radiation theory. Therefore, in the presence of attacking reagent, one bond is lost and this negatively charged attacking reagent links to the carbon having positive charge.
