$LiF$

Vedclass · Answer

(A) Lattice energy is inversely proportional to the inter-ionic distance between the cation and the anion. Since the fluoride ion $(F^{-})$ is common in all the given compounds,the lattice energy depends on the size of the alkali metal cation. As the size of the cation increases from $Li^{+}$ to $Cs^{+}$,the inter-ionic distance increases,leading to a decrease in lattice energy. Therefore,$LiF$ has the smallest inter-ionic distance and consequently the highest lattice energy.
