Which of the following has maximum Hydration power?
Correct answer: C. Be2+
- A. Na+
- B. K+
- C. Be2+
- D. Ca+2
Explanation
Hydration energy is the amount of energy released when one mole of ions undergoes hydration.Be2+ ion has small size and high charge. Hence, it has high polarizing power and can attract several water molecules. Thus it has the highest hydration energy among the given ions.

About Chemical Bonding
Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
