Electron movement in organic reactions

All organic reactions can be understood by following the electron movements, i.e. the electron redistribution during the reaction.

Electron movement in organic reactions

 

All organic reactions can be understood by following the electron movements, i.e. the electron redistribution during the reaction. The electron movement depends on the nature of the substrate, reagent and the prevailing conditions. The flow of electrons is represented by curved arrows which show how electrons move as shown in the figure. These electron movements result in breaking or formation of a bond (sigma or pi bond). The movement of single electron is indicated by a half -headed curved arrows.

There are three types of electron movement viz.,

·           lone pair becomes a bonding pair.

·           bonding pair becomes a lone pair

·           a bond breaks and becomes another bond.

Type 1: A lone pair to a bonding pair


Type 2: A bonding pair to a lone pair


Type 3: A bonding pair to an another bonding pair
