Question
Which of the following is not an amorphous allotrope of carbon?
- Lump black
- Blood charcoal
- Gas carbon
- Fullerenes
Hint:
It is used as lubricant and in solar cells. It has the formula C60.
The correct answer is: Fullerenes
The correct option is d)Fullerenes.
Fullerenes are molecules of carbon atoms with a hollow shape. Their structure is based on hexagonal rings of carbon atoms linked by covalent bonds. Some fullerenes contain rings with 5 or 7 carbon atoms. It's two examples of fullerenes are Buckminster fullerenes and nanotubes.
