Question

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

Answer 1

Correct Answer - A
`TX + Y rarr ` No reaction
`TX + Z rarr` No reaction
`TY + X rarr TX +Y`
`TY + Z rarr TZ + Y`
`TZ + X rarr TX + Z`
Ease of oxidation
`Y^(-) gt Z^(-) gt X^(-)`
