Q. Among the following carbon allotropes, the one with discrete molecular structure is
(A) Diamond
(B) a-Graphite
(C) b-Graphite
(D) Fullerene
Ans: Fullerene
Solution:
Allotropes of carbon like Diamond, Graphite, and Fullerene show crystalline structures. Fullerene has infinite lattices of Diamond and Graphite. It is formed by nanotubes forming the discrete molecular structure.
