What is a characteristic of simple molecular lattices?

Simple molecular lattices are characterized by small molecules arranged in a regular pattern, held together primarily by weak intermolecular forces such as Van der Waals forces or hydrogen bonds. The molecules themselves are typically covalently bonded within, but the forces that hold these molecules together in the lattice structure are relatively weak compared to the strong covalent bonds found in more complex structures like giant covalent lattices or ionic compounds.

This characteristic leads to several observable properties of substances with simple molecular lattices, such as low melting and boiling points, as these weak forces can be overcome with relatively little energy. Moreover, these structures do not conduct electricity because the molecules do not have free-moving charged particles, unlike ionic compounds or metals that typically show significant electrical conductivity due to their structure and bonding.

The other options describe features that do not apply to simple molecular lattices: coordinated frameworks refer to more complex structures seen in covalent solids; strong covalent bonds linking individual atoms is a feature of giant covalent lattices rather than simple molecular ones; and significant electrical conductivity is not observed in simple molecular substances due to the lack of free ions or electrons.
