For a molecule to possess a dipole moment,which following condition is necessary but not sufficient?

Question

Quizplus · Accepted Answer

The presence of one or more polar bonds is necessary for a molecule to possess a dipole moment, but it is not sufficient. The molecule must also have a spatial arrangement (geometry) where the individual dipole moments do not cancel each other out. This can happen with both linear and non-linear structures, and the presence of oxygen or fluorine alone is not sufficient for a dipole moment. The number of atoms in the molecule or the absence of a carbon-carbon double or triple bond are not relevant to determining the presence of a dipole moment.
