Relationships Between Polarity and Intermolecular Forces
The polarity and intermolecular bonds in a diamond correspond with the physical properties of diamond. A diamond is a cluster of carbon atoms, where 1 carbon is bonded to 4 others. In this crystallized structure, the intermolecular bonds between the atoms are non-polar because the electronegativity values of carbon are all the same throughout and result in a difference of 0. These intermolecular bonds between the carbon atoms create a structure in which there are very few free electrons because they are all covalently bonded together causing a very low conductivity of electricity but a high thermal conductivity. The structure of the diamond also influences other physical properties as the carbons in the structure are arranged in a tetrahedral shape. This explains the high melting point, boiling point and hardness as covalent bonds hold atoms tighter than an ionic bonds attraction, ("Hardness of Diamond").
