Which has the strongest and weakest ionic bonds among the following? $$LiI, NaI, KI, CsI$$

A$$KI, NaI$$
B$$CsI, LiI$$
Correct Answer
C$$KI, LiI$$
D$$CsI, NaI$$

Solution

In $$LiI$$, lattice energy of $$Li$$ is more than $$Cs$$ in $$CsI$$. Moreover lattice energy is inversely proportional to the atomic radii. Hence, $$LiI$$ will have the strongest ionic bond and $$CsI$$ the weakest.
