Question

Given below are two statements: one is labelled asAssertion (A) and the other is labelled as Reason (R). Assertion (A): Lithium salts are hydrated. Reason (R): Lithium has higher polarizing power than other alkali metal group members. In the light of the above statements, choose the most appropriate answer from the options given below : + (A) Both (A) and (R) are correct but (R) is NOT the correct explanation of (A). (B) (A) is correct but (R) is not correct . (C) (A) is not correct but (R) is correct. (D) Both (A) and (R) are correct and (R) is the correct explanation of (A).

Answer: D) BOTH (A) AND (R) ARE CORRECT AND (R) IS THE CORRECT EXPLANATION OF (A).

💡 Solution & Explanation

Lithium salts are hydrated due to high hydration energy of Li . Due to smallest size in IA group, Li has highest polarizing power.
