Heterolytically
Heterolytically is an adverb describing a mode of bond cleavage in chemistry in which the two electrons of a bond are not shared equally. Instead, both electrons are transferred to one of the fragments, generating a charged species such as a cation and an anion. This is contrasted with homolytic cleavage, in which each fragment retains one electron and neutral radicals are formed.
In organic reaction mechanisms, heterolytic bond breaking is common when a leaving group departs in a polar
Factors that favor heterolysis include highly polar solvents, stabilization of ions by solvation or resonance, and
Note on use: the term heterolytically is used to describe the manner of bond cleavage rather than
