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

Answer

C

Explanation

Oxidising tendency `prop (1)/("electrode potential ")`
TX `rarr` No reaction
TY `rarr` X,Z
TZ `rarr` X
`rarr` order of electrode potential is TY `lt` TZ `lt` TX
`rarr` order of oxidation of the anion is `y^(-) gt Z^(-) gt X^(-)`
