Answer 1

To determine which pair of elements would likely form the least polar bonds, we need to look at the electronegativity values of each element in the pairs provided.

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

The smallest difference in electronegativity indicates the least polar bond. Therefore, the pair that would form the least polar bonds is:

Bromine and Nitrogen (with a difference of 0.2).

So the answer is: bromine and nitrogen.
