The stability of peroxide and superoxide of alkali metals increase as we go down the group. Explain giving reason. |
|
Answer» Solution : The stability of peroxides and SUPEROXIDES increases as the size of metal ion increases. `KO_(2) lt RbO_(2) lt CsO_(2)` LI gives only monoxide, Na gives peroxide and K, Rb and Cs give superoxide also. Peroxide ion and superoxide ion combine with large size of alkali metals. Stability increases as the size of cation increases. `underset("Oxides")(O_(2)^(2-)) overset((1)/(2)O_(2))to underset("Peroxide")(O^(2-)) overset(O_(2)) tounderset("Super oxide")( 2O_(2)^(-))` |
