Vedclass · Answer

(A) The stability of alkali metal superoxides $(MO_2)$ increases as the size of the alkali metal cation increases. This is because the large cation stabilizes the large superoxide anion $(O_2^-)$ through lattice energy effects. The ionic radii of the alkali metals follow the order: $K^+ Therefore,the stability order is $KO_2 < RbO_2 < CsO_2$.

What is the correct stability order of $KO_2$,$RbO_2$,and $CsO_2$?
