State True or False for the following statements:
$(i)$ Positive and negative ions are formed by homolytic cleavage of a covalent bond.
$(ii)$ Positive and negative ions are formed by heterolytic cleavage of a covalent bond.
$(iii)$ Only homolytic cleavage is possible in the $C-Cl$ bond of $CH_3-Cl$.
$(iv)$ If heterolytic cleavage of a bond occurs,then ionic or polar type reactions take place.

(N/A) $(i)$ False: Homolytic cleavage results in the formation of free radicals,not ions.
$(ii)$ True: Heterolytic cleavage results in the formation of a carbocation and a carbanion (ions).
$(iii)$ False: Heterolytic cleavage is preferred in the $C-Cl$ bond of $CH_3-Cl$ due to the electronegativity difference between $C$ and $Cl$.
$(iv)$ True: Heterolytic cleavage generates charged species,which typically undergo ionic or polar reactions.
