X and Y are non mtals in which M shell is valence shell . Y is precedent to X . X shows uninegative valence . Identify the formulae of the compounds formed when X and Y react with divalent metal M.

A

`MX_(2),MY`

B

`MX,MY_(2)`

C

`M_(3)X_(2),M_(2)Y_(3)`

D

`M_(2)X_(3),M_(3)Y_(2)`

Text Solution

Verified by Experts

The correct Answer is:
1
Electronic configuration of X is 2 , 8 , 7
Electronic configuration of Y is 2 , 8 , 6
`:.` Valencies of X and Y are 1 and 2 respectively.
`M^(+2)X^(-)" "M^(+2)Y^(-2)`
`MX_(2) " " MY`
