Which of the following bonds will have the largest difference in electronegativity?

Question

Quizplus · Accepted Answer

To determine the largest difference in electronegativity, we need to look at the electronegativity values of the atoms involved. B has the highest electronegativity value (3.98) and Na has the lowest (0.93), resulting in a great difference in electronegativity. The other options have smaller differences in electronegativity. HBr has a difference of 0.73, H₂ has a difference of 1.41, and HS^- has a difference of 1.53.
