Methane molecule non-polarity

Référence de la vidéo 11937899
Animation of a model of a molecule of methane (CH4), showing the net distribution of electric charge around it. The perfect symmetry of the tetrahedral methane molecule leaves it with no external dipole, and it is classified as non-polar. At a macroscopic level, intermolecular attraction between opposite poles of polar molecules mean that they typically have higher melting and boiling points that non-polar compounds. Compare this situation with a molecule of ammonia, in clip K004 3634.
