Among the following compounds, which has the maximum lattice energy?
The correct option is C LiF
An estimate of the strength of the bond in an ionic compound can be obtained by measuring the lattice energy of the compound, which is the energy given off when oppositely charged ions in the gas phase come together to form a solid.
Lattice energy of ionic compounds is inversely proportional to the size of the ions involved. As LiF has the smallest cation and anion, LiF has the maximum lattice energy.
