Which element exhibits the allotropes Diamond, Graphite, and Fullerenes?
Answer and explanation
Correct answer: B. Carbon
- Step 1: Carbon atoms form diverse covalent network and cage structures due to catenation and hybridization versatility. Step 2. Diamond (sp^3 tetrahedral network), graphite (sp^2 layered sheets), and fullerenes (C60 cages) are classic allotropes of carbon. Answer: Carbon. Why not the others: Silicon does not form graphite-like allotropes; Phosphorus has white, red, and black allotropes; Sulfur has rhombic and monoclinic allotropes.
