In chemistry, heterolysis is chemical bond cleavage of a neutral molecule generating a cation and an anion. In this process the two electrons that make up the bond are assigned to the same fragment

A:B -> A⁺ + B^-

The energy involved in this process is called heterolytic bond dissociation energy. Bond cleavage is also possible by a process called homolysis. In heterolysis additional energy is required to separate the ion pair. An ionising solvent helps reduce this energy.
