$$Be{F_2}$$ is soluble in water whereas fluorides of other alkaline earth metals are insoluble because of
A.
ionic nature of $$Be{F_2}.$$
B.
covalent nature of $$Be{F_2}.$$
C.
greater hydration energy of $$B{e^{2 + }}\,ion$$ as compared to its lattice energy.
D.
none of these.
Answer :
greater hydration energy of $$B{e^{2 + }}\,ion$$ as compared to its lattice energy.
Solution :
$$B{e^{2 + }}$$ being small in size is heavily hydrated and heat of hydration exceeds the lattice energy. Hence $$Be{F_2}$$ is soluble in water.
