    Which of the following organometallic compound is\[\sigma \]and\[\pi -\]bonded?

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

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

    C)  \[{{[Co{{(CO)}_{5}}N{{H}_{3}}]}^{2+}}\]

    D)  \[Al{{(C{{H}_{3}})}_{3}}\]

    Correct Answer: C

    Solution :

                    CO ligand is bonded to the metal through\[\sigma \]and\[\pi -\]bonding. Hence,\[{{[Co{{(CO)}_{5}}N{{H}_{3}}]}^{2+}}\]organometallic   compound   has   both\[\sigma \]and \[\pi -\]bond.
