in Organic Chemistry Curve Arrow Notation Explains Electron Flow in Acid-Base and Radical Reactions

Curved arrow notation serves as a formal theoretical mechanism in organic chemistry for representing electron flow during chemical reactions and bond cleavages. The core principle dictates that full arrows represent the movement of two electrons (heterolytic processes) while half-arrows denote single-electron transfer, typically associated with radical reactions involving homolytic cleavage. This notation systematically illustrates transitions between reactants and products by mapping changes in electron density from nucleophilic regions to electrophilic centers based on electronegativity differences.
