Fullerene is an allotrope of Fluorine or Carbon?
Step 1:
Allotropy is defined as the existence of a chemical element in one or two forms having the same chemical properties but different physical properties are known as allotropy.
These forms are referred to as allotropes.
Step 2:
Fullerene is the form of carbon having a large hollow cage spheroidal molecule consisting of sixty or more atoms.
The closed three-dimensional allotropes of carbon are called fullerenes.
The carbon atom in fullerene is connected by single or double bonds.
Example: Buckminsterfullerene has the formula is a non-crystalline allotrope of carbon. It has a football-like structure.
Fluorine is a halogen atom. Fullerene is not an allotrope of fluorine.
Thus, fullerene is an allotrope of carbon.
