Which one of these polar covalent bonds would have the greatest percent ionic character?
A)H -Br
B)H - Cl
C)H - F
D)H- I

Question

Quizplus · Accepted Answer

The bond with the greatest percent ionic character is the one with the largest difference in electronegativity between the two atoms. Fluorine (F) is the most electronegative element, so the H-F bond has the greatest difference in electronegativity, resulting in the highest percent ionic character.
