A complex compound in which the oxidation number of a metal is zero, is

Options

  1. AK ₄ [ Fe ( CN )₆ ]
  2. BK ₃ [ Fe ( CN )₆ ]
  3. C[ Ni ( CO )₄ ]
  4. D[ Pt ( NH ₃ )₄ ] Cl ₂

Correct answer

C. [ Ni ( CO )₄ ]

Step-by-step solution

The oxidation number of Ni metal is zero in complex Ni ( CO )₄ . As CO is a neutral ligand i.e., Ni ( CO )₄ array r x+4(0)=0 x=0 array
