Which cation in each set is expected to have the larger (more negative)hydration energy? I.Be²⁺ or Ca²⁺ II.Rb⁺ or Zn²⁺ A)Be²⁺ in set I and Rb⁺ in set II B)Be²⁺ in set I and Zn²⁺ in set II C)Ca²⁺ in set I and Rb⁺ in set II D)Ca²⁺ in set I and Zn²⁺ in set II

Question

Quizplus · Accepted Answer

Be²⁺ has a smaller ionic radius and higher charge density than Ca²⁺, leading to a more negative hydration energy. Zn²⁺ has a higher charge and smaller size compared to Rb⁺, resulting in a more negative hydration energy.
