Which ion has the highest polarizing power?
Correct answer: B. Al3+
- A. Mg2+
- B. Al3+
- C. Ca2+
- D. Na+
Explanation
A small cation has more polarizing power. Polarising power depends upon size of cation and charge of cation so higher the charge of cation and lower the size of cation have higher polarising power. So, Al+3 have highest polarising power.

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.
