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 phosphorus and bromine nitrogen and oxygen

Explanation:

Step1: Recall bond - polarity rule

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

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

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

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

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

Step4: Calculate $\Delta\chi$ for phosphorus - bromine

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

Step5: Calculate $\Delta\chi$ for nitrogen - oxygen

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

Step6: Compare $\Delta\chi$ values

The smallest $\Delta\chi$ is 0.2 for bromine and nitrogen.

Answer:

bromine and nitrogen
