Non-polar molecules are those with even distribution of charges i.e., they do not have charged ends or poles.
Covalent Bonding: This is when atoms share electron pairs equally resulting in non-polarity.
London Dispersion Forces (Van der Waals forces): These are weak intermolecular forces arising from instantaneous dipoles in adjacent atoms/molecules.
Symmetry in Chemistry: Symmetrical structures often lead to nonpolar compounds because electric charges are evenly distributed.
