Question

Quizplus · Accepted Answer

The Br-Br bond is the least polar because both Br atoms have the same electronegativity value (2.8), so the electron pair is shared equally between them, resulting in a nonpolar covalent bond. The other bonds listed have different electronegativity values, resulting in varying degrees of polarity.
