In which of the following a covatent bond is not likely to exist?
Correct answer: C. CaO
- A. Br
- B. SiF
- C. CaO
- D. SeH2
Explanation
A covalent bond is not likely to exist in CaO. Calcium is a metal, and oxygen is a non-metal. When a metal reacts with a non-metal, it typically forms an ionic bond rather than a covalent bond. Therefore, CaO is more likely to have an ionic bond.

About Dipole Moment
Dipole moment measures the separation of positive and negative charge in a bond or molecule, with magnitude related to charge and distance, μ = q r. Questions distinguish polar bonds from polar molecules by considering bond direction, molecular geometry and whether individual bond moments cancel through symmetry.
