Question:
The oxidation state of nickel in [Ni(CO)_4] is
The oxidation state of nickel in [Ni(CO)_4] is
Show Hint
For metal carbonyl complexes like [Ni(CO)_4], the metal typically has an oxidation state of 0 because CO is a neutral ligand.

The Correct Option is D
Solution and Explanation
In the complex \([Ni(CO)_4]\), the CO molecule is a neutral ligand and does not contribute to the charge. Since CO is neutral, the oxidation state of Ni must be 0 in order to balance the charge of the complex, which is also neutral. Thus, the oxidation state of nickel in [Ni(CO)_4] is 0.
