A) MgO
B) CaO
C) SrO
D) BaO
Correct Answer: A
Solution :
Lattice energy \[\propto \] charge of ion \[\propto \frac{1}{size\text{ }of\text{ }ion}\]On moving downward, the size of alkaline earth metals increases due to increase in number of shells. Thus, Mg has the smallest size. Hence, lattice energy is highest for MgO.
