Vedclass · Answer

(C) The dipole moment of a molecule is a vector quantity. For a molecule to have a net dipole moment of zero,the individual bond dipoles must cancel each other out due to the symmetry of the molecule. In $trans-1, 2-$ Dichloroethylene,the two $C-Cl$ bonds are oriented in opposite directions at an angle of $180^{\circ}$ to each other. Since the electronegativity of $Cl$ is greater than $C$,the bond dipoles point towards the $Cl$ atoms. Because the molecule is centrosymmetric,these two equal and opposite bond dipoles cancel each other out,resulting in a net dipole moment of $\mu = 0$.

Which of the following molecules has a net dipole moment of zero?
