Question
Which one of the following allotropes have football like structure?
- Diamond
- Fullerene
- Graphite
- Charcoal
Hint:
It is used in lubricants and also in solar cells.
The correct answer is: Fullerene
The correct option is b)Fullerene.
Fullerenes are composed of 20 hexagonal and 12 pentagonal rings, forming the basis of a closed cage structure with icosahedral symmetry. The structure looks like a football. Each carbon atom bonds to three other carbon atoms to form an sp2 hybrid. The C60 molecule has two bond lengths. The 6:6 ring bond can be considered a "double bond" and is shorter than the 6:5 bond.
