If Y is the more electronegative atom, it will take both electrons during heterolytic fission. Here between reactants and products, an intermediate is created, which is a narrow unstable species.Īssume WY is a covalently bound molecule. The reaction has two intermediates: a carbocation and a carbanion. The anion is called carbanion when the carbon has a negative charge. Whenever a positive charge is present on the carbon in an organic molecule, the cation is called a carbocation. One of the products of heterolytic fission of a neutrally charged molecule has a positive charge, whereas the other has a negative charge. Heterolytic fission also referred to as heterolysis, is a kind of bond fission in which a covalent connection between two reactive species is broken unevenly, with one chemical species retaining the bond pair of electrons while the other does not. ![]() In the second circumstance, X preserves the bond pair and becomes the anion, while Y becomes the cation. Y preserves the bond pair of electrons in the first case, making it an anion and X a cation. The two ways that a molecule XY might undergo Heterolytic fission are depicted in the diagram below. The term 'heterolysis' is Greek in origin and approximately translates to 'unequal breaking.' Another name for it is homolytic cleavage.

The bond dissociation energies of these intramolecular bonds are quite low, indicating that they are weak. One such example is Homolytic breakage of the chlorine-chlorine bonds in peroxides.
