Vedclass · Answer

(A) The stability of oxides,peroxides,and superoxides of alkali metals depends on the size of the cation. As the size of the alkali metal cation increases down the group,the lattice energy increases,which stabilizes the larger anions. Therefore,the stability order for these compounds is: $Normal \ oxide  Peroxide > Superoxide$ due to the increasing charge density and decreasing size of the anion. However,considering the general trend of formation and stability across the group,the correct order is $Normal \ oxide > Peroxide > Superoxide$.

The stability order of oxide,peroxide,and superoxide of alkali metals is:
