Simple molecular melting and boiling points
Webbin melting points in terms of bonding and structure. In your answer you should use appropriate technical terms, spelled correctly. SiO2 is giant covalent (lattice) SiCl4 is simple molecular (lattice) van der Waals’ forces in SiCl4 Covalent bonds broken in SiO2 Forces OR bonds are stronger in SiO2 (than in SiCl4) WebbIntermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances.
