Methane molecules

Référence de la vidéo 11938267
Animation showing methane molecules. Each molecule is colour-coded to show its polarity. Methane is a symmetrical molecule, which makes it non-polar: there is separation of electric charge over its surface. This phenomenon means the individual molecules do not attract each other strongly, which is responsible for many of its physical properties, such as its low boiling point. Compare this situation with that of the similar compounds water and ammonia, in clips K004 4142 and K004 4147.
