Why is $lithium$ superoxide $(LiO_2)$ not possible?
(N/A) The stability of superoxides increases with an increase in the size of the alkali metal cation due to the increase in lattice enthalpy.
$Lithium$ $(Li^+)$ has a very small ionic radius,which results in a lower lattice enthalpy for $LiO_2$ compared to the superoxides of larger alkali metals.
Therefore,$LiO_2$ is thermodynamically unstable and does not exist under normal conditions.
