Which molecule has a dipole moment of zero?

Question

Quizplus · Accepted Answer

The molecule trans-ClHC=CHCl has a dipole moment of zero because the two carbon-chlorine bonds are pointing in opposite directions and cancel each other out. In option A and B, there is a chlorine atom which is highly electronegative and pulls electrons towards it, creating a dipole moment. Option C has a cis-arrangement of the double bond and hydrogen atoms which will result in a dipole moment. Therefore, the correct answer is option D.
