The correct order of stability for the following superoxides is

A

`KO_(2) gt RbO_(2) gt CsO_(2)`

B

`KO_(2) gt CsO_(2) gt RbO_(2)`

C

`CsO_(2) gt RbO_(2) gt KO_(2)`

D

`RbO_(2) gt CsO_(2) gt KO_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Stability of superoxides increases with increase in size and electropositivity of the metal. Hence the order `CsO_(2) gt RbO_(2) gt KO_(2)`.
