Question

Select correct statement (s) : 

(A) stability of peroxides and superoxides of alkali metals increases with increase in size of the metal ion 

(B) increase in stability in (A) is due to stabilisation of large anions by larger cations through lattice energy effects. 

(C) the low solubility of LiF is due to its high lattice energy whereas low solubility of CsI is due to smaller hydration energy . 

(D) NaOH does not form hydrated salt.
