Which of the following bonds has the smallest dipole moment?
A)Li-Cl
B)C-H
C)O-H
D)H-Cl

Question

Quizplus · Accepted Answer

The dipole moment depends on the difference in electronegativity and the bond length. In option B, the bond between C and H is nonpolar because of the negligible electronegativity difference, and the S-F bond is polar. The dipole moments of the polar bonds cancel each other out due to their opposite directions, resulting in a net dipole moment close to zero. Therefore, option B has the smallest dipole moment.
