Vedclass · Answer

(C) binary compound is a chemical compound composed of two different elements. Elements that exhibit variable oxidation states can form more than one type of binary compound with a given non-metal. $K$ (potassium) is an alkali metal with a fixed oxidation state of $+1$,forming only $KCl$. $Ca$ (calcium) is an alkaline earth metal with a fixed oxidation state of $+2$,forming only $CaCl_2$. $Zn$ (zinc) is a transition metal but exhibits a fixed oxidation state of $+2$ in its compounds,forming only $ZnCl_2$. $Fe$ (iron) is a transition metal that exhibits variable oxidation states of $+2$ and $+3$. Therefore,$Fe$ can form two types of binary compounds with chlorine: $FeCl_2$ (iron$(II)$ chloride) and $FeCl_3$ (iron$(III)$ chloride). Thus,the correct option is $C$.

Among $K, Ca, Fe,$ and $Zn$,the element which can form more than one binary compound with chlorine is
