Answer:
See explanation and image attached.
Explanation:
A free radical reaction is a reaction that involves species having an odd number of electrons.
The initiation step involves the formation of the odd electron species. The propagation steps produce more odd electron species while the termination steps eliminate the odd electron species.
The halogenation of alkanes occurs by free radical mechanism. The initiation, propagation and termination steps for the free radical chlorination of cyclohexane and cyclobutane is shown in the image attached.
