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.
