Solution

The correct option is C Assertion is correct but Reason is incorrect
Option (C) is correct.
$L i C l$ is covalent due to high polarising power of ${L i}^{+}$ .
According to Fajan 's rule, the smaller the size of cation and the larger the size of anion, greater is the polarising power and hence greater is the covalent character.
