When the intermolecular forces are strongest
Describe when the intermolecular forces are strongest? Briefly state it.
Expert
The intermolecular forces are the dipole-dipole, dispersion and hydrogen bonds. Such forces are much weaker than the chemical (or covalent) bonds. Thus molecular solids are soft, and encompass a generally low melting temperature.
