Strong covalent bonds, weak forces of attraction. 1 of 5 What are the properties of molecules? The result of the weak intermolecular forces is that they have low melting and boiling points. 2 of 5 What are macromolecules? Giant covalent structures with no charge. 3 of 5 What are the properties of macromolecules? Strong covalent bonds, high melting and boiling points.
