  • question_answer
    The correct order of the calculated spin-only magnetic moments of complexes (A) to (D) is
    (A) \[Ni{{\left( CO \right)}_{4}}\]
    (B) \[\left[ Ni{{\left( {{H}_{2}}O \right)}_{6}} \right]C{{l}_{2}}\]
    (C) \[N{{a}_{2}}\left[ Ni{{\left( CN \right)}_{4}} \right]\]
    (D) \[PdC{{l}_{2}}{{\left( PP{{h}_{3}} \right)}_{2}}\]
    [JEE MAIN Held on 08-01-2020 Evening]

    A) \[\left( A \right)\approx \left( C \right)\approx \left( D \right)<\left( B \right)\]

    B) \[\left( C \right)\approx \left( D \right)<\left( B \right)<\left( A \right)\]

    C) \[\left( A \right)\approx \left( C \right)<\left( B \right)\approx \left( D \right)\]

    D) \[\left( C \right)<\left( D \right)<\left( B \right)<\left( A \right)\]

    Correct Answer: A

    Solution :

    Correct order of the calculated spin only magnetic moments of complexes A to D is  \[(A)\simeq (C)\simeq (D)<\text{B}\]
