    Small quantities of solutions of compounds TX, TY and TZ are put into separate test tubes containing X, Y and Z solution. TX does not react with any of these. TY reacts with both X and Z. TZ reacts with X. The decreasing order of state of oxidation of the anions \[{{X}^{-}},{{Y}^{-}},{{Z}^{-}}\]is

    A) \[{{Y}^{-}},{{Z}^{-}},{{X}^{-}}\]               

    B) \[{{Z}^{-}},{{X}^{-}},{{Y}^{-}}\]

    C) \[{{Y}^{-}},{{X}^{-}},{{Z}^{-}}\]               

    D) \[{{X}^{-}},{{Z}^{-}},{{Y}^{-}}\]

    Correct Answer: A

    Solution :

    [a] \[Oxidising\text{ }tendency\propto \frac{1}{Electrode\text{ }potential}\] \[TX\xrightarrow{{}}No\text{ }reaction\] \[TY\xrightarrow{{}}X,Z\] \[TZ\xrightarrow{{}}X\] \[\Rightarrow \] order of electrode potential is \[TY<TZ<TX\] \[\Rightarrow \] Order of oxidation of the anion is \[{{Y}^{-}}>{{Z}^{-}}>{{X}^{-}}\]
