(a) Buckminsterfullerene is an allotrope of carbon, containing clusters of 60 carbon atoms joined together to form spherical molecules. Buckminsterfullerene burns on heating to form carbon dioxide and nothing is left behind. This shows that it is made up of carbon only like diamond and graphite.
Graphite and diamond are two of the most interesting minerals. They are identical chemically – both are composed of carbon (C), but physically, they are very different. Minerals which have the same chemistry but different crystal structures are called polymorphs.
What is the difference between diamond graphite and buckminsterfullerene?
Diamond is a giant macromolecular structure, whereas graphite is a layered structure of hexagonal rings. C60 fullerene consists of spheres made of atoms arranged in hexagons. Diamond has covalent bonding, whilst graphite and C60 fullerene have covalent bonding and London dispersion forces.
Diamonds are made of carbon so they form as carbon atoms under a high temperature and pressure; they bond together to start growing crystals. … That’s why a diamond is such a hard material because you have each carbon atom participating in four of these very strong covalent bonds that form between carbon atoms.
What is the difference between fullerene and buckminsterfullerene?
is that fullerene is (inorganic chemistry) any of a class of allotropes of carbon having hollow molecules whose atoms lie at the vertices of a polyhedron having 12 pentagonal and 2 or more hexagonal faces while buckminsterfullerene is an allotrope of carbon having a hollow molecule consisting of 60 atoms arranged in 12 …
What element do diamonds and graphite have in common?
Organic compounds are substances that contain carbon. There is a vast array of natural and synthetic organic compounds because of the ability of carbon to form four covalent bonds. Carbon can also form giant covalent structures, including diamond and graphite .
What are the differences between graphite and diamond?
Diamond and graphite are allotropes of carbon. These have different chemical and physical properties. The main difference between diamond and graphite is that diamond is made out of sp3 hybridized carbon atoms whereas graphite is made out of sp2 hybridized carbon atoms.
What are 3 differences between diamond and graphite?

Are diamond and graphite allotropes?
Diamond, graphite and fullerenes (substances that include nanotubes and ‘buckyballs’ , such as buckminsterfullerene) are three allotropes of pure carbon.
Is graphite to diamond spontaneous?
According to thermodynamics, the reaction from diamond to graphite is spontaneous and favorable. However, because kinetics rather than thermodynamics is controlling this reaction, it occurs extremely slowly. So, diamond is kinetically stable, but thermodynamically unstable.
Do diamonds decay into graphite?
Diamonds degrade to graphite, because graphite is a lower-energy configuration under typical conditions. … The degradation of diamond to graphite is a simple case of the atoms internally rearranging and relaxing to a lower energy state. This process requires no chemical reaction with an external material.
Is graphite formed Endothermically from diamond?
The conversion of diamond into graphite is an endothermic reaction.
