The World of Carbon
- Allotropes of Carbon
- Allotropes have different appearances and physical properties, but chemically they are the same.
- There are three allotropes of carbon: diamond, graphite, and buckminsterfullerene.

Amorphous Solid:
- An amorphous solid is a non-crystalline solid with no well-defined ordered structure.
- Amorphous forms of carbon are: Charcoal, Lampblack or soot; Coal; Coke
Amorphous form:
-
Charcoal: when a solid organic compound is heated in controlled supply of air, it leaves behind a grey porous residue called charcoal.
-
Wood charcoal: It is prepared by destructive distillation of dry wood. It is grey brittle solid, porous in nature, bad conductor of heat and electricity, adsorbs gases, liquids and solids and has a density of 1.5gcm-3.
-
Bone Charcoal: It is prepared by destructive distillation of powder obtained from dried bones of dead animals. It is extensively used in decolourising sugarcane j…
