heterolysis

Heterolysis is a chemical process where a compound breaks down into two oppositely charged particles or ions. This occurs when a covalent bond, formed by shared electrons, splits between two atoms. In heterolysis, one atom retains both electrons from the bond, resulting in a negatively charged ion (anion), while the other atom is left without electrons, becoming a positively charged ion (cation). This is distinct from homolysis, where the bond splits evenly, with each atom retaining one electron and forming free radicals. Heterolytic mechanisms are crucial in many chemical reactions, particularly in organic chemistry, where they lead to the formation of intermediates like carbanions.123
