Expert Answer:

lithium iodide is more covalent than lithium chloride because the electronegativity in halogens is in the following sequence F>Cl>Br>I.
Thus flourine is most electronegative while iodine is least in halogens.
Covalent character of bond increases down the group so i.e. F
Therefore lithium iodide is more covalent than lithium chloride.
