The bonding pair of electrons is equally shared between the atoms in:
Correct answer: D. H2
- A. HF
- B. H2O
- C. HCI
- D. H2
Explanation
In hydrogen gas (H2), the bonding pair of electrons is equally shared between the two hydrogen atoms. Hydrogen is diatomic, meaning it exists as H2, and it forms a non polar covalent bond since the two hydrogen atoms have equal electronegativity.

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.
