Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is Graphite.
Key Points
- Graphite is an allotrope of carbon known for its soft and slippery texture.
- It consists of layers of carbon atoms arranged in a hexagonal lattice, connected by weak van der Waals forces, which allow the layers to slide over each other.
- Graphite is widely used as a lubricant and in pencils due to its ability to leave marks on paper.
- Unlike diamond, which is hard and rigid, graphite has a much lower hardness due to its layered structure.
- Its electrical conductivity is high, making it useful in applications such as electrodes and batteries.
Additional Information
- Diamond:
- Diamond is another allotrope of carbon, known for its extreme hardness and brilliant optical properties.
- It has a tetrahedral crystal structure, where each carbon atom is bonded to four other carbon atoms.
- Diamonds are widely used in jewelry and industrial cutting tools.
- Buckminsterfullerene:
- Also known as "buckyballs," this allotrope consists of carbon atoms arranged in a spherical shape (C60 molecule).
- It has unique properties, including high chemical stability and potential applications in nanotechnology.
- Van der Waals Forces:
- These are weak forces of attraction between molecules or layers, such as those found between layers of graphite.
- They are responsible for the slippery texture of graphite.
- Applications of Graphite:
- Used in batteries, lubricants, and as a moderator in nuclear reactors.
- Its thermal and electrical conductivity make it valuable in high-tech industries.
