Which one contains non polar covalent bond?
Correct answer: D. All of these
- A. H2
- B. CI2
- C. N2
- D. All of these
Explanation
Among the molecules H2 (hydrogen gas), Cl2 (chlorine gas), and N2 (nitrogen gas), all of them contain non polar covalent bonds. In a non polar covalent bond, the electrons are equally shared between the two atoms. These molecules consist of two identical atoms, so the electronegativity difference between the atoms is effectively zero, resulting in nonpolar covalent bonds. In all these cases, the bonding pairs of electrons are equally shared between the two atoms, resulting in non polar covalent bonds.

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.
