Free radicals have a free reactive oxygen on its molecule that wants to bind to something so it can be stable. Radicals attach to your cells and 'steal' and break down the lipid membrane that holds your cells together. This causes the cells to lyse (leak) and eventually causes tissue damage.

Reactive Oxygen Species (ROS) are molecules in our body that prevent this.

What are some examples of radical?

Hydrogen Peroxide is an example of a free radical. A free radical works by causing the oxidation of another atom. Free radicals are highly reactive because they are missing an electron. They will take that electron from any plant, human, or animal atom in a cell. That atom is then missing an electron and becomes a free radical itself. When any compound has the suffix -oxide in it, that usually hints that it is a free radical and would be considered basic on the pH scale.

What are the 3 steps in the free radical substitution?

The three steps in free radical substitution are initiation, propagation, and termination. In initiation, a free radical is generated. In propagation, the free radical reacts with a molecule to form a new free radical. In termination, two free radicals react with each other to form a stable product, ending the chain reaction.

Why peroxide effect is not observed with Cl?

Because carbon and iodine elements have same electronegativities and after formation of free radicals, mobility of carbon free radical is much higher than iodine free radical. So carbon free radical can easily attack to form more stable free radical with the substrate. Secondly, due to larger size iodine free radical can easily dimerize to give iodine molecule. Hence, we can not observe peroxide effect
