Chemical Properties

Which one of the following super oxide is most stable


MO2(super oxides) are paramagnetic with one unpaired electron in pi anti bonding molecular orbital;

MO2(super oxides) are yellow (or) orange in colour 

Lithium forms monoxides

Sodium with limited oxygen forms monoxide and with excess oxygen forms peroxide;

K, Rb and Cs form super oxides. Stability of super oxides increases with increase in cation size. This fact is explained by Lattice enthalpy effects.
