Which best indicates the direction of the dipole moment in acetone, (CH₃)₂C=O? A)drawing (1) B)drawing (2) C)drawing (3) D)drawing (4)

Question

Quizplus · Accepted Answer

In drawing (2), the dipole moments of the C=O bond and the C-C bond are oriented in opposite directions, creating a net dipole moment for the entire molecule. In drawings (1), (3), and (4), the dipole moments of the bonds either cancel each other out or are not significant enough to determine the overall dipole moment of the molecule.
