| Re: Melting/Boiling points
The way I understand it, the larger the molecule, the more electrons that are displaced to create the temporary dipole and hence the greater the force between molecules.
In order for a substance to melt and then boil, intermolecular forces must be overcome. Thus, the stronger the intermolecular forces, the higher the melting/boiling points.
Consequently, the larger the molecule, the higher the melting and boiling points of that substance. |
