Which reaction will need maximum energy to remove its one electron?
Correct answer: D. C2+→ C3+ + e-
- A. Na → Na++ e-
- B. Ca → Ca++ e-
- C. K → K++ e-
- D. C2+→ C3+ + e-
Explanation
In Option D, an electron is being removed from an already positively charged ion, not a neutral atom like the others. The nuclear attraction experienced by the outer electrons would be stronger due to the positive charge, so more energy would be required to remove an electron.

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.
