In the reaction of Cl₂ with ethane and UV light, which of the following reactions would be a chain termination event(s) ?
I. Cl∙ + CH₃-CH₃→ CH₃-CH₂-Cl + H∙
II. Cl∙ + CH₃-CH₃→ CH₃-H₂C∙ + HCl
III. Cl∙ + CH₃-H₂C∙ → CH₃-CH₂-Cl
IV. Cl₂ + CH₃-H₂C∙ → CH₃-CH₂-Cl + Cl∙
V. Cl_{2 + UV light}→ C l∙ + Cl∙

Quizplus · Accepted Answer

Chain termination occurs when two radicals combine to form a stable molecule, ending the chain reaction. In reaction III, Cl∙ and CH₃-H₂C∙ combine to form CH₃-CH₂-Cl, terminating the chain.
