A compound `(MO_(2))` of group I element (M ) hydrolysed to form `M^(+) ,OH^(-) ,X ` and Y . When X reacts with `I_(2)` in basic medium the products formed are `I^(-)` water and Y. Then X and Y respectively

Options

A. `H_(2) O_(2),O_(2)`
B. `H_(2)O_(2),O_(3)`
C. `H_(2),O_(2)`
D. `O_(2),H_(2)`

Answer

A

Explanation

Given
A compound `(MO_(2)) ` of group 1 element (M ) hydrolysed to give `M^(+) OH^(-) X ` and Y when ( x) reacts with `I_(2)` in basic medium it gives `I^(-)` water and (Y) Thus (x) and (y) are `H_(2) O_(2)` (x ) and `O_(2)` (y) respectively
The reaction involved are as follows
`MO_(2) + 2H_(2) O to 2M^(+) + 2OH^(-) =H_(2) O`
`I_(2) H_(2) O_(2)+ 2OH^(-) to 2I^(-) + 2H_(2) O + O_(2) `
Hence option (a) is the correct answer .
