Vedclass · Answer

(C) To determine the oxidation state of the central metal atom,we set the sum of oxidation states equal to the charge of the complex:$(A)$ For $[Cu(NH_3)_4]SO_4$:$x + 4(0) - 2 = 0 \implies x = +2$$(B)$ For $[Pt(NH_3)_2Cl_2]$:$x + 2(0) + 2(-1) = 0 \implies x = +2$$(C)$ For $[Ni(CO)_4]$:$x + 4(0) = 0 \implies x = 0$$(D)$ For $K_3[Fe(CN)_6]$:$3(+1) + x + 6(-1) = 0 \implies 3 + x - 6 = 0 \implies x = +3$Since the oxidation state of $Ni$ in $[Ni(CO)_4]$ is $0$,it is a zero-valent metal complex. Therefore,option $C$ is correct.

Which of the following compounds is a zero-valent metal complex?
