Answer:

The answer to your question is: b. P - Br

Explanation:

Difference of electronegativities from the periodic table. The one with the highest electronegativity will be the most polar.

H = 2.2

Se = 2.55

Electronegativity = 2.55 - 2.2 = 0.35

P = 2.19

Br = 2.96

Electronegativity = 2.96 - 2.19 = 0.77

N = 3.04

I = 2.66

Electronegativity = 3.04 - 2.66 = 0.38
