    Which of the following is incorrect statement regarding \[A={{[Co{{(en)}_{2}}C{{l}_{2}}]}^{+}}\] and\[B={{[Co{{(N{{H}_{3}})}_{4}}C{{l}_{2}}]}^{+}}\]?

    A)  A is more thermodynamically stable than B.

    B)  A shows optical isomerism.

    C)  A and B both are diamagnetic

    D)  A is outer orbital complex while B is inner orbital complex.

    Correct Answer: D

    Solution :

    (1) Due to chelate effect A is more thermodynamically stable. (2) C is isomer of \[{{[Co{{(en)}_{2}}C{{l}_{2}}]}^{+}}\] shows optical isomerism. (3) \[C{{o}^{3+}}=3{{d}^{6}}\,\,\,\,{{t}_{2g}}\,\,\,\,\,{}^{222}{{e}_{g}}{{\,}^{0,0}}\] (4) (A) and (B) both are inner orbital complex.
