    An aqueous solution of titanium chloride, when subjected to magnetic measurement, measured zero magnetic moment. Assuming the octahedral complex in aqueous solution, the formulae of the complex is:           

    A) \[\left[ Ti{{\left( {{H}_{2}}O \right)}_{6}} \right]C{{l}_{2}}\]      

    B) \[\left[ Ti{{\left( {{H}_{2}}O \right)}_{6}} \right]C{{l}_{4}}\]

    C) \[\left[ TiC{{l}_{3}}{{\left( {{H}_{2}}O \right)}_{3}} \right]\]      

    D) \[\left[ TiC{{l}_{2}}{{\left( {{H}_{2}}O \right)}_{4}} \right]\]

    Correct Answer: B

    Solution :

    [b] \[\left[ Ti{{\left( {{H}_{2}}O \right)}_{6}} \right]C{{l}_{4}}\] Coordination number \[6\Rightarrow \] octahedral complex Ti is in +4 oxidations state \[\Rightarrow \] no unpaired electrons \[\Rightarrow \] magnetic moment = 0 B.M.
