ANSWER

Lithium-ion has a small size. Hence it can easily distort the electron cloud of the anion. Hence lithium halides have partial covalent character.

The anion with a larger size can be easily distorted. The increasing order of the ionic size is Cl

−

<Br

−

<I

−

. Hence among the given halides, lithium chloride is least covalent in nature and lithium iodide is most covalent in nature.

Hence, the correct option is D
