S-S bond is present in which of the ion pairs?
Correct answer: D. Option D
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Each sulfur atom has six valence electrons. In S2O72-. Each sulfur atom shares two pairs of electrons with two oxygen atoms, leaving two unshared electrons on each sulfur atom. These unshared electrons repel each other, making it impossible for the two sulfur atoms to form a covalent bond with each other. Option D is correct.

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.
