    The geometry of \[Ni\,{{(CO)}_{4}}\] and \[[Ni\,{{(PP{{h}_{3}})}_{2}}]\,C{{l}_{2}}\] are

    A) both square planar

    B) tetrahedral and square planar respectively

    C) both tetrahedral

    D) square planar and tetrahedral respectively

    Correct Answer: C

    Solution :

    \[Ni\,{{(CO)}_{4}};\]Oxidation state of \[Ni=0\]
    As \[CO\]is a strong ligand and hence pairing of electrons occurs.
    Oxidation state of \[Ni\] in \[[Ni\,{{(PP{{h}_{3}})}_{2}}]\,C{{l}_{2}}\] is \[x+0\times 2+(-2)=0\]
    As both the complexes has \[s{{p}^{3}}\text{-}\]hybridisation, thus their geometry is tetrahedral.
