# What is "molecularity"? And how does "molecularity" relate to the melting point/boiling point of a substance?

On the other hand, network covalent solids, such as diamond or graphite, have exceptionally high melting points, that again can be attributed to the strong $C - C$ bonds that make up the solid in 2 or 3 dimensions. Both metals, and network covalent substances exhibit little molecularity.
