The cleavage of a bond ('homolytic cleavage' or 'homolytic fission') so that each of the molecular fragments between which the bond is broken retains one of the bonding electrons. A
It is the reverse of
unimolecular
reaction involving homolysis of a bond (not forming part of a cyclic structure) in a molecular entity containing an even number of (paired) electrons results in the formation of two radicals: ![Not defined](/img/inline/H02851.png)

. Homolysis is also commonly a feature of bimolecular substitution reactions
(and of other reactions) involving radicals and molecules.See also:
