Some examples of fullerenes include buckminsterfullerene (C60), which is a soccer ball-shaped molecule composed of 60 carbon atoms, and carbon nanotubes, which are cylindrical fullerenes. Another example is the fullerene derivative known as C70, which consists of 70 carbon atoms arranged in a spherical structure.

What are the appearance of carbon?
Carbon has many forms. Soot, graphite, fullerenes, Buckeyballs, nanotubes, for some examples.
Who discovered fullerenes?
Fullerenes are named after William Buckminster Fuller, a designer and philosopher who theorized their existence and uses.
How are fullerenes prepared?
Fullerenes are prepared by vaporizing graphite rod in helium atmosphere. A mixture of fullerenes like C60, C70 etc are formed which are separated by solvent extraction method.C60 is obtained by column chromatography using alumina as the adsorbent and hexane as the solvent.
What is the structure of fullerenes?
what is the structure of Buckminster fullerene
Why is fullerene usual?
Today fullerenes are not usually used compounds.
What do diamonds. Graphite and fullerenes have in common?
All forms of carbon.
What element is present in buckminsterfullerene?
Fullerenes are complex carbon containing molecules.
What is the chemical symbol for one molecule of fullerene?
Fullerenes are a class of compounds.
Are fullerenes solid at room temperature?
Yes, they strongly resemble soot.
Major improvements in field of chemistry?
Modern examples: discovery of noble gases chemistry, VSEPR theory, discovery of fullerenes, organic electrical conductors, liquid crystals, nucleic acids structure, insulin synthesis, etc.
What form of carbon can a nanotube be compared?
A carbon nanotube can be compared to the fullerenes, a group of spherical carbon allotropes (allotropes are different forms of a single element).The key difference is that the fullerenes are spherical in shape whereas carbon nanotubes resemble a fullerene network that has been stretched into a cylindrical shape. Furthermore, nanotubes contain more carbon atoms than most fullerenes do.
Similarities between Graphite and Fullerenes?
