A fullerenes or Buckminster Fullerene ( footballene) is a spherical allotrope of carbon.

At its simplest it is 60 (sixty) carbon atoms arranged in hexagons and pentegons, anf the whole is then integrated into a spherical shape. Similar to the shape patterns on an Association Football.

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.


Why do forms of carbon have different properties?

Different forms of carbon, such as diamond, graphite, and fullerenes, have distinct properties because of variations in their molecular structures. For instance, diamond has a tetrahedral lattice structure that makes it the hardest natural substance, while graphite has layers of hexagonally arranged carbon atoms that allow for easy cleavage and conductivity. Fullerenes have a spherical or tubular structure, giving them unique properties such as high strength and potential for nanotechnology applications.


Who discovered fullerenes?

Fullerenes are named after William Buckminster Fuller, a designer and philosopher who theorized their existence and uses.


What are the different types of carbon polymorphs and how do they differ from each other?

There are three main types of carbon polymorphs: diamond, graphite, and fullerenes. Diamond is a hard, transparent crystal structure with each carbon atom bonded to four others in a tetrahedral arrangement. Graphite has a layered structure with each carbon atom bonded to three others in a hexagonal pattern, giving it a slippery feel. Fullerenes are molecules made of carbon atoms arranged in a hollow sphere or tube shape, such as buckyballs or carbon nanotubes. These polymorphs differ in their atomic arrangement, bonding structure, and physical properties.


What are the three allotropic form of carbon?

1. Amorphous form - Example : Coal2. Crystalline form - Example : DiamondandThe third one is something called "buckminsterfullerenes" or commonly known as Fullerenes which was discovered in 1985.

Are fullerenes solid at room temperature?

Fullerenes can exist in different forms at room temperature, including solids, liquids, and gases. The most common form of fullerenes found at room temperature is solid, such as C60 which has a fullerene structure.


Examples of fullerenes?

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 does the atomic structure of carbon form?

Carbon can form diamond, graphite, amorphous carbon, nanotubes, fullerenes, etc.


Why fullerenes are electrophilic?

Fullerenes are electrophilic because the carbon atoms in the fullerene cage have pi bonds that can easily accept electrons. This makes fullerenes susceptible to reacting with nucleophiles that donate electrons, resulting in electrophilic addition reactions. Additionally, the curvature of the fullerene structure can distort the electron density, making certain carbon atoms more electron-deficient and thus more electrophilic.


What is the shape of pure carbon fullerenes?

Pure carbon fullerenes have a spherical shape, often resembling a soccer ball or geodesic dome. They are made up of interconnected carbon atoms arranged in hexagonal and pentagonal patterns, creating a cage-like structure.


How are crystals of fullerenes obtained from soot?

Crystals of fullerenes are obtained from soot using a technique called solvent extraction. The soot is mixed with a suitable solvent, such as toluene or carbon disulfide, to dissolve the fullerenes. By applying techniques like filtration or centrifugation, the fullerenes can be separated from the other components of the soot and then allowed to crystallize out of the solution.

Are fullerenes strong?

Yes, fullerenes are known for their remarkable strength and stability. Their unique molecular structure, which consists of carbon atoms arranged in a spherical or cylindrical shape, imparts exceptional mechanical properties. This makes them not only strong but also lightweight, leading to potential applications in materials science, nanotechnology, and medicine. However, their strength can vary depending on the specific type of fullerene and its arrangement.


Why is fullerene usual?

Today fullerenes are not usually used compounds.
