This is a step in a free radical chain reaction. Name this step
Initiation Free radicals are formed
This is a step in a free radical chain reaction. Name this step
Termination Free radicals are used up
This is a step in a free radical chain reaction. Name this step
Propagation Free radicals are both used up and formed
Atoms or molecules that are highly reactive due to the presence of unpaired electrons.
Free radicals
Molecules that react with free radicals to form stable molecules and prevent chain reactions from occurring.
Free radical scavengers
Name the three steps of free radical chain reactions
Initiation, propagation, termination
Free radical scavengers
Molecules that react with free radicals to form stable molecules and prevent chain reactions from occurring.
