Question

use the table to answer the question. elements with their electronegativity element electronegativity bromine 2.8 oxygen 3.5 nitrogen 3.0 phosphorus 2.1 based on the information in the table, which pair of elements would likely form the least polar bonds with each other? (1 point) oxygen and phosphorus bromine and nitrogen nitrogen and oxygen phosphorus and bromine

Explanation:

Step1: Recall bond - polarity rule

The polarity of a bond depends on the electronegativity difference ($\Delta\chi$) between the two elements. The smaller the $\Delta\chi$, the less polar the bond.

Step2: Calculate $\Delta\chi$ for oxygen and phosphorus

$\Delta\chi_{O - P}=3.5 - 2.1=1.4$

Step3: Calculate $\Delta\chi$ for bromine and nitrogen

$\Delta\chi_{Br - N}=3.0 - 2.8 = 0.2$

Step4: Calculate $\Delta\chi$ for nitrogen and oxygen

$\Delta\chi_{N - O}=3.5 - 3.0=0.5$

Step5: Calculate $\Delta\chi$ for phosphorus and bromine

$\Delta\chi_{P - Br}=2.8 - 2.1 = 0.7$

Step6: Compare the differences

We compare the values: $0.2<0.5<0.7<1.4$

Answer:

B. bromine and nitrogen
