define the homolysis in breif
Answers
Answer:
The term homolysis generally means breakdown to equal pieces.
Answer:
The term homolysis generally means breakdown (lysis) to equal pieces (homo = same). 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. There are separate meanings for the word in chemistry and biology:
• Homolysis (biology), the fact that the dividing cell gives two equal-size daughter cells.
• Homolysis (chemistry), a chemical bond dissociation of a neutral molecule generating two free radicals.
Explanation:
One such example is the homolytic cleavage of the oxygen-oxygen bonds in peroxides. These intramolecular bonds are fairly weak, implying that they have very small bond dissociation energies. Therefore, this barrier can be overcome with only a small amount of heat energy.
