2.3 Structure and Bonding of Carbon
Diamond
Giant covalent structure
4 covalent bonds per carbon atom
Properties
Very hard
Rigid structure
Very high melting point
Strong covalent bonds
Does not conduct electricity
No charged particles
Graphite
Giant covalent structure
3 covalent bonds per carbon atom
Delocalised electron per carbon atom
Conducts electricity
High melting point
Strong covalent bonds
Layers of hexagonal rings
No covalent bonds between layers
Layers slide over each other
Soft and slippery
Graphene
Used to make composites
Very strong
One layer of graphite
Sheet of carbon atoms
Very light
Conducts electricity due to delocalised electrons
Fullerenes
Buckminsterfullerene
Hollow sphere
Carbon atoms arranged in hexagonal rings
Can also form rings of 5 or 7 carbon atoms
Uses
Good catalysts
Deliver drugs into the body
Nanotubes
Electronics and composites
High length to diameter ratio
Hollow shapes
