Answer #1

Answer : LiF < MgO

Explanation

Lattice energy depends on the charge of the constituent ions. In MgO, the charge of cation and anion are +2 and -2 respectively.In LiF, the charge of cation and anion are +1 and -1. Similarly, if the electronegativity of the anion is higher, the higher will be the lattice energy. Also, an ionic compound with smaller cation size will have higher lattice energy.

Here, the correct order is,

LiF > LiI

NaCl > KCl   

MgO > CsCl  

CaO > BaCl2

LiF < MgO
