Solution

Allotropic forms of carbon:
Carbon shows allotropy and its allotropic forms are categorized into two groups; amorphous and crystalline forms.
All other forms of carbon except diamond, graphite, and fullerene are amorphous forms.
Thus, Charcoal is an amorphous form of carbon having a highly porous structure with great adsorbing capacity.
Therefore, Charcoal is an amorphous form of carbon.
