Hi there,
The compounds consist of Large anions such as I- the solubility can decrease with the increase in the cationic size of the Compound. On another hand, Alkaline Metals the decrease in association energy is a lot of fast than the decrease in lattice energy with the rise within the size of the ion. The solubility of alkaline Metal iodides could be in the following order :
LiI > NaI > KI > rbi > CsI
Hope it helped.

Answer: CsI < RbI < KI < NaI < LiI
Explanation:
According to Fajan's rule, larger cation/anion bonded with smaller anion/cation has greater solubility.
