    Which of the following coordination compound is incapable of showing geometrical isomerism?

    A) \[[PtC{{l}_{2}}{{(N{{H}_{3}})}_{2}}]\]          

    B) \[{{[CoC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]}^{+}}\]

    C) \[[Co{{(N{{O}_{2}})}_{3}}{{(N{{H}_{3}})}_{3}}]\]    

    D) \[{{[Co{{(en)}_{3}}]}^{3+}}\]

    Correct Answer: D

    Solution :

    [D] \[{{[Co{{(en)}_{3}}]}^{3+}}\] only show optical isomerism\[PtC{{l}_{2}}{{(N{{H}_{3}})}_{2}}\] cis & trans platin \[{{[CoC{{l}_{2}}{{(N{{H}_{3}})}_{4}}]}^{+}}\] cis trans \[[Co{{(N{{O}_{2}})}_{3}}{{(N{{H}_{3}})}_{3}}]\] facial & meridinial
