Which of the following is true of bond polarity?
A) A bond is nonpolar if the electronegativities of the bonded atoms are unequal.
B) The bond polarity decreases with an increasing difference in electronegativity.
C) A bond is polar if the bonded atoms have equal electronegativities.
D) The ionic character increases with an increasing difference in electronegativity.
E) There is no direct correlation between electronegativity and bond polarity.

Question

Quizplus · Accepted Answer

Bond polarity is directly related to the difference in electronegativity between the bonded atoms. The greater the difference, the more polar the bond, with a difference of 0.4 or greater resulting in an ionic bond. Therefore, as the electronegativity difference increases, the bond polarity and ionic character also increase.
