Primary valence and secondary valence of central metal [Ni(CO)4] is :

• Primary valency - It is the valency of central metal in which no. of negative ions are required to satisfy the charge on the metal atom.

• Secondary valency - It is the number of molecules attached to the central atom by coordinate bond.

• In [ Ni(CO)4 ], CO is a neutral molecule.

°•° Oxidation state of of Ni = 0

• Primary valency = 0

No. of molecules attached to Ni = 4

• Secondary valency = 4.

Answer 2

Answer:

Zero

Explanation:

CO is a neutral molecule. Hence, it's oxidation state is zero. Thus, Nickel also has zero oxidation state.
