Allotropes are different structural types of the same element and therefore can exhibit different physical and chemical properties.
-
Carbon has the following allotrope
-
Graphite- It is a soft, black single-layered hexagonal lattice
-
Diamond-Tetrahedral geometry and is a poor conductor of electricity.
-
Fullerene- Also known as 'buckyballs'.
-
Graphene - It is a basic structural element of other allotropes like nanotubes, etc.
-
Carbyne- linear acetylenic carbon allotrope.
-
Chaoite
- It is also known as White carbon.
- It was discovered from the Ries crater in Bavaria.
- It has a dihexagonal dipyramidal structure.
- It is not an allotrope of carbon.
