Chapter - 2.4.1

Graphite

Each carbon atom in graphite is bonded to three others forming layers of hexagons, leaving one free electron per carbon atom which becomes delocalized
The covalent bonds within the layers are very strong, but the layers are attracted to each other by weak intermolecular forces

Properties Of Graphite

Each carbon atom is bonded to three others forming layers of hexagonal-shaped forms, leaving one free electron per carbon atom
These free (delocalised) electrons exist in between the layers and are free to move through the structure and carry charge, hence graphite can conduct electricity
The covalent bonds within the layers are very strong but the layers are connected to each other by weak forces only, hence the layers can slide over each other making graphite slippery and smooth
Graphite thus:
- Conducts electricity
- Has a very high melting point
- Is soft and slippery, less dense than diamond
Graphite is used in pencils and as an industrial lubricant, in engines and in locks
