Which of the following order is/are CORRECT.
Options:(select one or more)
Answer:
A, D
Solution:
(A) Ionic radius: Correct. Down the group size increases, so Na⁺ < K⁺.
(B) Hydration energy: Incorrect. Smaller ions have higher hydration energy, so Na⁺ > K⁺.
(C) Polarizing power: Incorrect. Polarizing power decreases with increase in size, so Na⁺ > K⁺.
(D) Electrical conductance in aqueous solution: Correct. Due to lower hydration and higher mobility, K⁺ shows greater conductance than Na⁺.
Correct Answer: (A), (D)
