Anomalous Behavior of Lithium Halogens

Assertion :Li...

Question

Assertion :Lithium halides are covalent in nature. Reason: $L i^{+}$ ion due to its smaller size than other alkali metalcations exerts stronger polarizing power towards an ion and therefore develops covalent character in the molecule (Fajan's rule).
