NEET AIPMT SOLVED PAPER MAINS 2010

  • question_answer
    Which one of the following complexes is not expected to exhibit isomerism?    

    A) \[{{[Ni{{(N{{H}_{3}})}_{4}}{{({{H}_{2}}O)}_{2}}]}^{2+}}\]               

    B) \[[Pt{{(N{{H}_{3}})}_{2}}C{{l}_{2}}]\]

    C) \[[Ni{{(N{{H}_{3}})}_{2}}C{{l}_{2}}]\]      

    D) \[{{[Ni{{(en)}_{3}}]}^{2+}}\]

    Correct Answer: C

    Solution :

    \[\text{ }\!\![\!\!\text{ Ni(N}{{\text{H}}_{\text{3}}}\text{)C}{{\text{l}}_{\text{2}}}\text{ }\!\!]\!\!\text{ }\]has tetrahedral geometry and thus, does not exhibit isomerism due to presence of symmetry elements.
