Peroxides are often added to free-radical reactions as initiators because the oxygen–oxygen bond cleaves homolytically rather easily. For example, the bond-dissociation enthalpy of the \(\mathrm{O}-\mathrm{O}\) bond in hydrogen peroxide\((\mathrm{H}-\mathrm{O}-\mathrm{O}-\mathrm{H})\) is only 213 kJ/mol (51 kcal/mol). Give a mechanism for the hydrogen peroxide-initiated reaction of cyclopentane with chlorine. The BDE for \(\mathrm{HO}-\mathrm{Cl}\) is 210 kJ/mol (50 kcal/mol).

ANSWER:Step 1 of 4
The reaction of chlorine with cyclopentane in hydrogen peroxide involves three steps.
They are:
Chain initiation step,
Chain propagation step
Chain termination step.
