Accordingly, does fullerene have a high or low melting point?
They are made up of large molecules but do not have a giant covalent structure. Weak intermolecular forces exist between individual buckyballs. Little energy is needed to overcome these forces, so substances consisting of buckyballs are slippery and have lower melting points than graphite or diamond .
Furthermore, why does iodine have a low melting point? Iodine has a low melting point because of it's large size. I2 or iodine molecule has two iodine atoms bonded together. Since the size is very large,bonds are weak and melt under low temperature.
Subsequently, one may also ask, why does c60 have a low melting point?
Its molecules are made up of 60 carbon atoms joined together by strong covalent bonds. There are weak intermolecular forces between molecules of buckminsterfullerene. These need little energy to overcome, so buckminsterfullerene is slippery and has a low melting point.
What are the properties of fullerenes?
Their unique molecular structure results in extraordinary macroscopic properties, including high tensile strength, high electrical conductivity, high ductility, high heat conductivity, and relative chemical inactivity (as it is cylindrical and "planar" — that is, it has no "exposed" atoms that can be easily displaced).
