Question

# The charge on the central metal ion in the complex [Ni(CO)4] is 2403

Solution

## The correct option is C 0This is a neutral complex, so the charge on the metal + that on the ligands would be = 0. We also know that CO is a neutral ligand having a charge of 0. If x is the oxidation number of Ni then: x+4(0)=0 ∴ x = 0
