Question

Diamond graphite and fullerene are crystalline form of carbon​

Answer 1

yes, they all are allotrophs of carbon have crystalline properties

Answer 2

$\large \bold\red {Question}\Longrightarrow$

Explain the Diamond, graphite and fullerene are crystalline form of carbon.

$\huge \bigstar$$\huge\bold{\mathtt{\purple{✍︎A{\pink{N{\green{S{\blue{W{\red{E{\orange{R✍︎}}}}}}}}}}}}}$$\huge \Rightarrow$

1. (1) A crystalline form of carbon has a regular and definite arrangement of atoms (2) In diamond. each carbon atom is linked to four other carbon atoms by covalent bonds. Therefore, diamond has tetragonal three dimensional structure. In graphite, each carbon atom is bonded to three other carbon atoms in such a way that a hexagonal layered structure is formed. Thus, the regular arrangement of atoms in graphite is in layers. In fullerene, C atoms are joined to each other in pentagonal and hexagonal arrangements. As a result, the structure of fullerene is like a football. The molecules of fullerene are found in the form of buckyballs and buckytubes. (3) Since diamond, graphite and fullerene have definite shape, sharp edges and plane surfaces, they are in crystalline form.
