| Also Known As | Heterolysis, ionic cleavage, polar bond dissociation |
What is Heterolytic Cleavage?
The breaking of a covalent bond in which both electrons go to one atom, producing a cation and an anion (or a carbocation and a carbanion in organic chemistry). This type of bond breaking is common in polar reactions like SN1, SN2, E1, and E2 mechanisms.

Heterolytic cleavage mechanisms underpin all polar organic reactions: nucleophilic substitutions, eliminations, electrophilic additions, and acid-base reactions. Predicting which bond undergoes heterolytic cleavage based on polarity and leaving group ability is central to mechanistic organic chemist…
Reactions proceeding by heterolytic mechanisms often involve highly reactive cationic or anionic intermediates that can react with biological molecules. Strong acid catalysts and reactive leaving groups used in industrial heterolytic reactions require appropriate PPE and waste management.
