Question

Small quantities of solutions of compounds TX, TY and TZ are put into separete test tubes containing X,Y and Z solution. TX does not react with any of these. TY reacts with both X and Z. Does not react with any of these. TY reats with both X and Z. TZ reacts with X. the decreasing order of state of oxidation of the anions `X^(-),Y^(-),Z^(-)`
A. `Y^(-),Z^(-),X^(-)`
B. `Z^(-),X^(-),Y^(-)`
C. `Y^(-),X^(-),Z^(-)`
D. `X^(-),Z^(-),Y^(-)`

Answer 1

Correct Answer - A
Oxidizing tendency`prop(1)/("Electrode potential")`
`Txto`No reaction
`TY to X,Z`
`TZtoX`
`implies`Order of electrode potential is
`TY lt TZ lt TX`
`implies`Order of oxidation of the anion is
`Y^(-) gt Z^(-) gt X^(-)`.
