Work Step by Step
Chlorine has an electronegativity value of 3.0 whereas bromine has an electronegativity value of 2.8. The difference in electronegativity between the two elements is 0.2. If the difference is less than 0.4, then the bond is nonpolar. This means that the degree of charge separation between these two elements can be represented by the color yellow-green, representing a nonpolar bond where the electrons are shared equally between the two elements. Therefore, the correct representation of the bond between these two elements is (a).
