Explanation:
When we add chlorine to a substance or compound then this process is known as chlorination.
For example, a process of chlorination is as follows.
Initiation : 
where, Cl* is a free radical.
Propagation:
Termination:
Thus, we can conclude that out of the given options 
is not formed through a termination reaction in the chlorination of methane.
The ionization energy of an element is the amount of energy required to remove one mole of electrons from the element in its gaseous state. The equations for the first three are:
Fe(g) → Fe⁺(g) + e⁻
Fe⁺(g) → Fe⁺²(g) + e⁻
Fe⁺²(g) → Fe⁺³(g) + e
