Lithium lodide is the most covalent among the alkali metal halides . Give the reason.

Explanation

`Li^(+)` ion is small in size with more change density among alkali metal ions. So according to Fajan's rule it has more polarising power.`l^(-)`ion is bigger anion among haldide ions and can undergo more polarisation. So the lithium iodide is more covalent among alkali metal halides.
