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

    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 :

                    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 \[\pi \] electrons in their molecular orbitals.
