Solution

The correct option is A $B a (N O_{3})_{2}$
Solution:- (A) $B a {(N O_{3})}_{2}$
$B a {(N O_{3})}_{2}$ does not crystallise with water molecules as moving down the group, the possibility of formation of hydrate decreases with the decrease in charge density.

Q. The alkaline earth metal nitrate that does not crystallise with water molecules, is:

Q. Assertion :The crystalline salts of alkaline earth metals contain more water of crystallization than the corresponding alkali metal salts. Reason: The size of alkaline earth metal ions is lower than the size of alkali metal ions. The lower the size of the cation, the higher is the hydration energy. So the salts of alkaline earth metals have more water molecules of crystallization than those of alkali metals.

Q. Compare the solubility and thermal stability of alkali metals carbonates with those of the alkaline earth metals nitrates.
