Answer 2

(A). Mgo is the correct answer.

Therefore, Mgo has the highest lattice energy.

Explanation:

Among the given following compounds, MgO has the highest lattice energy. As 'Mgo' is a bi-bivalent ionic compound and Magnesium ions are smaller than sodium ions, and also oxide ions are smaller than chloride ions. As a result, the distance between the positive and negative ions is less in MgO than in NaCl, LiCl, and LiF and as a result, the forces of attraction will be greater in 'MgO'.

So, 'Mgo' has maximum lattice energy.

Hence, (A). Mgo is the correct answer.
