Open the interactive simulation →How to use this simulation
- Play the mechanism or step through each stage.
- Watch single-headed (fish-hook) arrows move one electron each.
- Count how many radicals each propagation step makes and uses.
What to notice
- UV light splits Cl₂ into two radicals (initiation).
- Propagation keeps the chain going; termination joins two radicals.
