Question

Quizplus · Accepted Answer

In molecule C, the oxygen (O) atom has a significantly larger electronegativity compared to the carbon (C) and hydrogen (H) atoms. This creates a polar covalent bond between the O and the H atoms, resulting in a significant dipole moment in the molecule. Molecules A and B do not have as large a difference in electronegativity between their atoms, resulting in smaller dipole moments.
