What are `X_- and Y_-` in the following reactions?
a) ` MnO_4^- + I^- rightarrow^(H+) X.`
b)` MnO_4^- + I^- rightarrow^(H_2O+) Y`

Options

A. `l_(2),lO(4)^(-)`
B. `l_(2),lO_(3)^(-)`
C. `lO_(3)^(-),lO_(3)^(-)`
D. `lO_(3)^(-),l_(2)`

Answer

B

Explanation

`:.` For (a)
(a) `2 MnO_(4)^(-) + 10l^(-) + 16H^(+) to 2Mn^(2+) + 5l_(2) + 8H_(2) O`
(b) ` 2MnO_(4)^(-) +l^(-)+ H_(2) O to 2MnO_(2) + 2OH^(-) + lO_(3)^(-)`
Hence, (X) and (Y) are respectively `l_(2) and lO_(3)^(-)`
