Explain electron movement in organic reactions.

Explanation

All organic reactions can be understood by following the electron movements.
(i) Lone oair becomes a bonding pair. (ii) Bonding pair becomes a lone pair. (iii) A bond breaks and becomes another bond.
The electron movement depends on the nature of the substrate, reagent and the prevailing conditions.
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.
