Small quantities of compounds TX, TY and TZ are put into separate test tubes containing X, Y and Z solutions. TX does not react with any of these. TY reacts with both X and Z. TZ reacts only with X. The decreasing order of ease of oxidation of the anions `X^(-),Y^(-) and Z^(-)` is

Options

A. `Y^(-),Z^(-),X^(-)`
B. `Z^(-),X^(-),Y^(-)`
C. `Y^(-),X^(-),Z^(-)`
D. `X^(-),Z^(-),Y^(-)`

Answer

a

Explanation

Since TX does not react with any of the solution it means that `X^(-)` is least easily oxidized since tY reacts with both X and Z i.r
`Y^(-) +XrarrX^(-)+Y` and `Y^(-)+ZrarrZ^(-)+Y` therefore `Y^(-)` is most easily oxidized since tZ reacts with ony X i.r `Z^(-)` is more easily oxidized than `X^(-)` combining all the result the decreasing order of oxidation of anions follows the order
`Y^(-)gtZ^(-)gtX^(-)`
