    Among the following, which is not the \[\pi \]-bonded organometallic compound?         [AIPMT 2003]

    A) \[Cr{{({{\eta }^{6}}-{{C}_{6}}{{H}_{6}})}_{2}}\]

    B) \[{{(C{{H}_{3}})}_{4}}Sn\]     

    C) \[K[PtC{{l}_{3}}\,({{\eta }^{2}}-{{C}_{2}}{{H}_{4}})]\]        

    D) \[Fe{{({{\eta }^{5}}-{{C}_{5}}{{H}_{5}})}_{2}}\]

    Correct Answer: B

    Solution :

    [b] In \[{{(C{{H}_{3}})}_{4}}Sn\] (organometallic compounds of tin) single bonds are present in form of sigma bond. \[\pi \] bonded organometallic compound includes organometallic compounds of alkenes, alkynes and some other carbon containing compounds having electrons in their molecular orbitals.
