Carbon has large number of allotropes of which crystalline forms are diamond, graphite and fullerenes. Amorphous forms are coal, coke wood charcoal animal charcoal, lamp black, gas carbon, petroleum coke, sugar charcoal (Atomic radius of C = 0.77A^(@) ) In graphite which have several fused hexagonal ring of benzene the hybridization state of each carbon atom and the bond order of each carbon-carbon bond are respectively

Elemetal carbon appears in many structural forms or allotropes. Three of these forms are crystalline - diamond, graphite and the recently discovered fullerene (bucky ball) - while more than 40 others including coke and carbon black are amorphous. Now there seems to be a fourth crystalline allotrope of carbon, reported in 1995 by Rich and Lagow at the University of Texas Newly discovered allotrope of carbon has the form

Elemetal carbon appears in many structural forms or allotropes.

Now there seems to be a fourth crystalline allotrope of carbon, reported in 1995 by Rich and Lagow at the University of Texas Structures of different allotropes of carbon have been compared. Which represents incorrect comparison ?

Carbon shows allotropy. The various allotropic forms of carbon can be broadly classified into 2 classes a) Crystalline form b) Amphorous form Diamond and Graphite are the 2 crystalline forms of carbon. In diamond, the carbon atoms are arranged tetrahedrally while in graphite, the carbon atoms are arranged inregular hexagons in flat parallel layers When diamond is heated at 1800 to 2000^(@)C in valency. It is converted into
