Why is lithium iodide more covalent than lithium fluoride ?

Text Solution

Verified by Experts

According to Fazan's rule, `Li^(+)` ion can polarise `I^(-)` ion more than the `F^(-)` ion because of the bigger size of the anion. Therefore, lithium iodide (LiI) has more covalent character than lithium fluoride (LiF).
