The key difference between diamond graphite and fullerene is that diamond has a diamond cubic crystal structure and graphite has a hexagonal crystal structure, while fullerene occurs as a large spheroidal molecule. Diamond, graphite and fullerene are different allotropes of the chemical element carbon.
In what way does the structure of fullerenes differ from the other forms of carbon diamond and graphite?
Fullerenes are forms of carbon, and include nanotubes and buckyballs . A nanotube resembles a layer of graphene, rolled into a tube shape. Nanotubes have high tensile strength , so they are strong in tension and resist being stretched.
Is fullerene more pure than diamond?
Fullerenes are pure carbons that are in the shape of spherical hollow cage like a soccer ball with 60 carbon atoms. It is the only pure form of molecular carbon utilized by our body. … (c) Coloured diamonds are costlier than colourless and transparent diamonds. (d) Graphite has layers of hexagonal carbon bondings.
What is fullerene how is it different from?
All are made up of only carbon atoms; the difference lies in the arrangement of Carbon atoms. Fullerene has a hollow ball-like or cage-like structure in which carbon atoms are joined to each other by double and single bonds. E.g. C60, 60 carbon atoms form an open cage.
a)Buckminsterfullerene is type of fullerenes with the formula C60. And as Diamond and Graphite are crystalline form of carbon and Buckminster fullerenes is also a form of crystalline form of carbon.
Why do fullerenes make good lubricants?
Buckyballs are good lubricants because of their spherical shape. Their hollow structure could make them useful for delivering medicine in the future. Carbon nanotubes are very strong and light, and can act as semiconductors or conductors.
Why are fullerenes good lubricants GCSE?
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 is the purest form of diamond?
The purest form is 24K, though ornaments are made with 18K or 22K gold. This means that other metals have been added to give it strength.
Why is fullerene the purest form of carbon?
The correct answer is Fullerene. The purest form of carbon is fullerenes since they have a smooth structure without dangling bonds. Fullerene is an allotrope of carbon having single and double carbon bonds forming a closed mesh.
Is fullerene a pure substance?
Fullerenes are molecules (pure substances made of only one type of atom) of carbon that can take on different shapes like tubes, spheres, cubes, etc. … It’s made up of only carbon, and there is always a hollow space inside the structure.
What are fullerenes explain?
A fullerene is an allotrope of carbon whose molecule consists of carbon atoms connected by single and double bonds so as to form a closed or partially closed mesh, with fused rings of five to seven atoms. … Cylindrical fullerenes are also called carbon nanotubes or buckytubes.
Where are fullerenes used?
Fullerenes are active molecules. Fullerene molecule can be used as an antioxidant because it can easily react with radicals due to the high affinity of the electron. At the same time, Fullerene is used as an anti-aging and anti-damage agent in the cosmetic sector. Fullerenes are used as antiviral agents.
What are Graphenes properties?
The most outstanding properties of graphene are:
- High thermal conductivity.
- High electrical conductivity.
- High elasticity and flexibility.
- High hardness.
- High resistance. …
- Ionizing radiation is not affected.
- Able to generate electricity by exposure to sunlight.
- Transparent material.
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 are 3 differences between diamond and graphite?

|5. It does not possess any lustre||5. It a has metallic lustre.|
|6. It a has very high melting point.||6. It has low metling point.|
What is the difference between graphene and fullerene?
Graphene is an allotrope of carbon that occurs as sheets of carbon while fullerene is an allotrope of carbon which occurs as spheres of carbon. The key difference between graphene and fullerene is that graphene has a two-dimensional structure, while fullerene has a three-dimensional structure.
