Among the following bonds,which would be the least polar? Electronegativity values are:
Na = 0.9,O = 3.5,F = 4.0,Cl = 3.0,Br = 2.8,I = 2.5

Question

Quizplus · Accepted Answer

The polarity of a bond is determined by the difference in electronegativity between the two atoms involved. The smaller the difference, the less polar the bond. In this case, Na has an electronegativity of 0.9, and I has an electronegativity of 2.5, making the difference 1.6, which is the smallest difference among the given options. Therefore, Na-I would be the least polar bond.
