Lithium iodide is more covalent than Lithium chloride. Give reason.

Text Solution

Verified by Experts

(i) The smaller cation and larger anion shows greater covalent character due to greater extent of polarisation.
(ii) The sizè of `Li^(+)` ion is smaller than `Na^(+)` ion and hence the polarising power or `Li^(+)` ion is more. So lithium chloride is more covalent than sodium chloride.
