To determine which pair of elements would likely form the least polar bonds, we need to consider the electronegativity differences between the elements in the pairs.
1. **Nitrogen and Oxygen**: Nitrogen has an electronegativity of about 3.0, while oxygen has an electronegativity of about 3.5. The difference is 0.5, which indicates a polar bond.
2. **Oxygen and Phosphorus**: Oxygen is again at about 3.5 and phosphorus is around 2.1. The difference here is 1.4, leading to a more polar bond.
3. **Phosphorus and Bromine**: Phosphorus is at 2.1, and bromine is around 2.8. The difference is 0.7, indicating a polar bond, but less polar than the previous one.
4. **Bromine and Nitrogen**: Bromine has an electronegativity of about 2.8, and nitrogen is at 3.0, giving a difference of 0.2, which indicates a very weakly polar bond, close to nonpolar.
Comparing these differences, the pair of **bromine and nitrogen** would form the least polar bonds since the electronegativity difference (0.2) is the smallest among the given pairs.
