Which of the following bonds is the least polar?
Correct answer: C. C....I
- A. B....Cl
- B. C....Cl
- C. C....I
- D. C....Br
Explanation
CI represents the bond between carbon (C) and iodine (I), which has the least electronegativity, resulting in the least polar 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.
