A complex compound in which the oxidation number of a metal is zero is
Options
- AK ₄ [ Fe ( CN )₆ ]
- BK ₃ [ Fe ( CN )₆ ]
- C[ Ni ( CO )₄ ]
- D[ Pt ( NH ₃ )₄ ] Cl ₂
Correct answer
C. [ Ni ( CO )₄ ]
Step-by-step solution
CO is a neutral ligand, so the oxidation state of metal in metal carbonyls is always zero. array r [ Ni ( CO )₄ ] x +(0 4)=0 x =0 array
