Answer 1

To determine which pair of elements would likely form the least polar bonds, we look at the difference in electronegativity between the pairs of elements. The smaller the difference, the less polar the bond.

Here are the electronegativities:

• Bromine (Br): 2.8
• Oxygen (O): 3.5
• Nitrogen (N): 3.0
• Phosphorus (P): 2.1

Now, let's calculate the differences in electronegativity for each pair:

1. Nitrogen and Oxygen: Difference = |3.0 - 3.5| = 0.5

2. Phosphorus and Bromine: Difference = |2.1 - 2.8| = 0.7

3. Bromine and Nitrogen: Difference = |2.8 - 3.0| = 0.2

4. Oxygen and Phosphorus: Difference = |3.5 - 2.1| = 1.4

Now, let's summarize the differences:

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

The pair with the smallest difference and thus the least polar bond is:

Bromine and Nitrogen (0.2).

So, the answer is bromine and nitrogen.
