Question

Quizplus · Accepted Answer

The polarity of a bond is determined by the difference in electronegativity between the two atoms involved. The greater the difference, the more polar the bond. Among the options, the O-H bond has the largest electronegativity difference (3.5 for O and 2.1 for H, a difference of 1.4), making it the most polar bond listed.
