The hydration energy of $$M{g^{ + + }}$$ is larger than that of :
A.
$$A{l^{3 + }}$$
B.
$$N{a^ + }$$
C.
$$B{e^{ + + }}$$
D.
$$M{g^{3 + }}$$
Answer :
$$N{a^ + }$$
Solution :
$$N{a^ + }$$ ion has larger size than $$M{g^{2 + }}$$ ion and hence hydration energy of $$M{g^{2 + }}$$ is larger than that of $$N{a^ + }$$.
