Question

differentiate between the crystalline form of carbon and non crystalline or amorphous form of carbon

Answer 1

Crystalline solids have following 

1.they have regular arrangement over a long range.

2.the give clean cleavage when cut with knife.

3.they possess sharp melting point.

4.they are Anisotropic in nature i.e value of given property is different in all direction.

5.Example: Quartz

*Amorphous solids have the following 

1.they have regular arrangement over a short range.

2.the give unclean cleavage when cut with knife.

3.they possess range melting point.

4.they are isotropic in nature i.e value of given property is same in all direction.

Answer 2

$\sf \large{answer} =$

Crystalline form of carbon is definite in molecular structure, but non-crystalline isn't. Molecules in non-crystalline form are arranged randomly without any fixed pattern or shape. This form is also called amorphous form of carbon. Diamond, Graphite, Fullerene, Buckyballs, Carbon Nanotubes, etc.

hope it helps❤
