$(c, a)$

Vedclass · Answer

(A) The $CN^-$ ion acts as a strong ligand,which facilitates the formation of stable coordination complexes with metal ions,hence it exhibits $(c)$ complexing property.It also acts as a reducing agent in many chemical reactions involving metal ions,as it can be oxidized to $(CN)_2$,hence it exhibits $(a)$ reducing property.Therefore,the $CN^-$ ion exhibits both $(a)$ reducing and $(c)$ complexing properties.

Which of the following properties are exhibited by the $CN^-$ ion towards metal compounds?
$(a)$ Reducing
$(b)$ Oxidizing
$(c)$ Complexing
