A covalent bond may be:
Correct answer: D. Both A and C
- A. 100% covalent
- B. 100% ionic
- C. Partially ionic
- D. Both A and C
Explanation
A covalent bond may be partially ionic or 100% covalent because the electrons that are shared between the two atoms may not be shared equally. In a 100% covalent bond, the electrons are shared equally between the two atoms. However, in a partially ionic bond, the electrons are shared unequally, with one atom having a slightly stronger pull on the electrons than the other atom.

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.
