Which of the following peroxides is not known ?

A

`BaO_(2)`

B

`SrO_(2)`

C

`CaO_(2)`

D

`BeO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
D
Peroxides are formed by group 2 elements wit increasing case and increasing stability as metal ions become larger because large cations stabilize lage anions by providing high lattice enthalpy. `BaO_(2)` is formed by passing air over `BaO` at `500^(@)C.SrO_(2)` is formed similarly but requires relatively higher temperature and pressure. `CaO_(2)` with `H_(2)O_(2)` and then dehydrating the product. Crude `MgO_(2)` is alos made using `H_(2)O_(2)` but no peroxide of Be is known,
