homolysis (homolytic)
homolysis (均勻分裂)

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 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:
It is the reverse of colligation. Homolysis is also commonly a feature of bimolecular substitution reactions (and of other reactions) involving radicals and molecules.

homolysis (均勻分裂)

Illustrated Glossary of Organic Chemistry

Homolytic bond cleavage (homolytic cleavage; homolysis): Bond breaking in which the bonding electron pair is split evenly between the products. Homolytic cleavage often produces radicals.


In the photolytic bromination of methane, the chain initiation mechanism step is an example of homolytic bond cleavage.
