Which of the following statements provides accurate justification for why a molecule can be neutral in charge, but contain partial charges on specific atoms?
A. The electronegativity values of the atoms in the molecule are so different that one atom loses a valence electron, resulting in a partially positive charge, while the other atom gains a valence electron, resulting in a partially negative charge.
B. With little to no differences in electronegativity values, the atoms in the molecules share electrons evenly, which results in no dipole moment.
C. Due to differences in electronegativity values, two atoms can share the valence electrons unequally, though the dipole moments that are formed provide symmetry to molecule.
D. When the difference in electronegativity values is low, a molecule is able to cancel the dipole moments by arranging its atoms asymmetrically.
