Part of the Fragrances and Skin Care topic from Unit 2 of Higher Chemistry, Nature's Chemistry
Atoms or molecules that are highly reactive due to the presence of unpaired electrons.
Free radicals
Free radicals
Atoms or molecules that are highly reactive due to the presence of unpaired electrons.
What causes this process to happen?
UV light
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.
