Question

Quizplus · Accepted Answer

Oxygen (O) and Fluorine (F) are both highly electronegative elements, but their electronegativities are very close to each other. This small difference in electronegativity between O and F leads to the formation of a covalent bond that is the least polar compared to the other options, where the differences in electronegativity between the elements are greater, resulting in more polar bonds.
