Question
Which allotrope of carbon has 2D hexagonal layered structure?
- Graphite
- Diamond
- Fullerene
- None of these
Hint:
It is soft and often used as lubricant. It is also used to make the lead of pencil.
The correct answer is: Graphite
The correct option is a)Graphite.
Graphite has a layered structure in which layers are alternately stacked vertically. Each layer of graphite has a hexagonal arrangement of atoms, with each carbon atom forming strong covalent bonds with the other three adjacent carbon atoms. Thus, graphite has a hexagonal layered structure.
