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.
