Which of the following complexes is used as an anti-cancer agent:

  • Option 1)

    mer-\left [ Co(NH_{3})_{3}Cl_{3} \right ]

  • Option 2)

    cis-\left [ PtCl_{2}(NH_{3})_{2} \right ]

  • Option 3)

    cis-K_{2}\left [ PtCl_{2}Br_{2} \right ]

  • Option 4)

    Na_{2}CoCl_{4}

 
As we learned in concept Geometrical Isomers - This is due to the difference in relative position of the ligands attached to the central metal atom with respect to each other -    Cis and is used as an anti cancer agent.   Option 1) This option is incorrect. Option 2) This option is correct. Option 3) This option is incorrect. Option 4) This option is incorrect.

  • Option 2)

    \left [ Fe(H_{2}O)_{6} \right ]^{3+}

  • Option 3)

    \left [ Co(H_{2}O)_{6} \right ]^{2+}

  • Option 4)

    \left [ Co(H_{2}O) _{6}\right ]^{3+}

 
As we learnt in  CFSE in octahedral complex - -    for Fe3+  we have     Option 1) Incorrect Option 2) Correct Option 3) Incorrect Option 4) Incorrect

Magnetic moment 2.83 BM is given by which of the following ions?

(At.nos. Ti = 22, Cr = 24, Mn = 25, Ni = 28)

  • Option 1)

    Ti3+

  • Option 2)

    Ni2+

  • Option 3)

    Cr3+

  • Option 4)

    Mn2+

 
As we discussed in the concept  For magnetic moment 2.83 BM the number of unpaired electrons should be two: Option 1) Ti3+ Option is incorrect Option 2) Ni2+ Option is correct Option 3) Cr3+ Option is incorrect Option 4) Mn2+ Option is incorrect
