Allotropy of carbon with questions that may arise
Accepted Answer
Carbon exhibits allotropy, meaning it exists in different structural forms with distinct physical and chemical properties. Here are the most common allotropes and questions that may arise:
Diamond:
Question: Why is diamond so hard?
Answer: Diamond's hardness stems from its strong covalent bonds forming a rigid, three-dimensional network structure.
Graphite:
Question: Why is graphite a good conductor of electricity?
Answer: Graphite's structure includes delocalized electrons that can move freely between the layers, allowing for electrical conductivity.
Fullerenes (e.g., Buckminsterfullerene, C60):
Question: What are fullerenes?
Answer: Fullerenes are closed-cage molecules composed entirely of carbon atoms, often forming spherical or ellipsoidal shapes.
Carbon Nanotubes:
Question: How are carbon nanotubes different from graphene?
Answer: Carbon nanotubes are one-dimensional, cylindrical structures formed by rolling up a single layer of graphene, while graphene is a two-dimensional sheet of carbon atoms.
Amorphous Carbon:
Question: What is amorphous carbon?
Answer: Amorphous carbon lacks a well-defined crystal structure, with examples including coal and charcoal.
