WitrynaMolecules containing polar bonds have no molecular polarity if the bond dipolescancel each other out by symmetry. Polar molecules interact through dipole–dipole intermolecular forcesand hydrogen bonds. … WitrynaAny planar molecule, such as benzene, has its molecular plane as a plane of symmetry because reflection across the molecular plane leaves all nuclei unmoved. NH 3 has three planes of symmetry each of which contains an N–H bond and is perpendicular to the plane containing the three hydrogen atoms.
