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

    A)  \[{{K}_{4}}[Fe{{(CN)}_{6}}]\]

    B)  \[{{K}_{3}}[Fe{{(CN)}_{6}}]\]

    C)  \[[Ni{{(CO)}_{4}}]\]

    D)  \[[Pt{{(N{{H}_{3}})}_{4}}]C{{l}_{2}}\]

    Correct Answer: C

    Solution :

    \[CO\]is a neutral ligand, so the oxidation state of metal in metal carbonyls is always zero. \[[Ni{{(CO)}_{4}}]\] \[x+(0\times 4)=0\] \[x=0\]
