Order of solubility of fluorides of alkaline earth metals in water is Halides of alkaline earth metals (except Be) are ionic solids and are therefore are water soluble and their solubility in water decreases from

M g

to Ba due to the decrease in the hydration energy.
However, fluorides of alkanline earth metals excepts

B e F_{2}

are almost insoluble in water.

Q. Correct order for solubility of alkaline earth metals in water is

$M g F_{2} > C a F_{2} > S r F_{2} > B a F_{2}$

$M g F_{2} < C a F_{2} < S r F_{2} < B a F_{2}$

$M g F_{2} > C a F_{2} < S r F_{2} < B a F_{2}$

$B a F_{2} > M g F_{2} > S r F_{2} > C a F_{2}$

Q. Correct order for solubility of alkaline earth metals in water is

MgF2​>CaF2​>SrF2​>BaF2​

MgF2​<CaF2​<SrF2​<BaF2​

MgF2​>CaF2​<SrF2​<BaF2​

BaF2​>MgF2​>SrF2​>CaF2​

$M g F_{2} > C a F_{2} > S r F_{2} > B a F_{2}$

$M g F_{2} < C a F_{2} < S r F_{2} < B a F_{2}$

$M g F_{2} > C a F_{2} < S r F_{2} < B a F_{2}$

$B a F_{2} > M g F_{2} > S r F_{2} > C a F_{2}$
