Quizplus · Accepted Answer

The greater the difference in electronegativity between two atoms in a bond, the shorter the bond length. In this case, since the 3rd atom in both molecules is P, the difference in electronegativity between the 1st and 2nd atoms will determine the bond length. Since the electronegativity of B is less than that of S, NO₃^- will have a longer bond length than NO₂^-.
