To determine which pair of elements would likely form the least polar bonds, we can examine the differences in electronegativity for each pair:

  1. Nitrogen (3.0) and Oxygen (3.5): Difference = 0.5
  2. Bromine (2.8) and Nitrogen (3.0): Difference = 0.2
  3. Oxygen (3.5) and Phosphorus (2.1): Difference = 1.4
  4. Phosphorus (2.1) and Bromine (2.8): Difference = 0.7

The pair with the smallest difference in electronegativity will form the least polar bond.

Comparing the differences:

  • Nitrogen and Oxygen: 0.5
  • Bromine and Nitrogen: 0.2
  • Oxygen and Phosphorus: 1.4
  • Phosphorus and Bromine: 0.7

The smallest difference is 0.2 for the pair bromine and nitrogen. Therefore, bromine and nitrogen would likely form the least polar bonds with each other.
