Question

Assertion :STATEMENT-1 : The lithium ion itself, and also its compounds, are more heavily hydrated than those of the rest of the group members. Reason: STATEMENT-2 : The $L{i}^{+}$ is smallest among alkali metals and polarise water molecules more easily than the other alkali metal ions.

• A. Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.
• B. Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1

Answer 1

The correct option is A Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.

Lithium ion and its compounds are heavily hydrated due to the small size of $L{i}^{+}$ ion among alkali metal ion and it easily polarizes the water molecules than other alkali metals.

Hence, option A is correct.
