We are asked to determine which of the following solids has the highest melting point: Ar(s), CCl4(s), LiCl(s), CH3OH(s).
Intermolecular forces of attraction (IMF) can be used to predict the melting point of substances.
The stronger the IMFs, the higher the Heat of Fusion (heat required for substances to melt).
Here are the relative strengths of the IMF’s of compounds:
Ionic bonding > H bonding > dipole-dipole > London dispersion (Van der Waals)
Which of the following solids has the highest melting point: Ar(s), CCl4(s), LiCl(s), CH3OH(s)?
