What to Focus On
- Carbon has electronic configuration 2,4 with valency 4
- Forms covalent bonds by sharing electrons, not ionic bonds
- Tetravalent nature allows formation of four bonds
- Diamond: 3D network, hardest natural substance, electrical insulator, thermal conductor
- Graphite: Layered structure, soft, good electrical conductor, used as lubricant
- Fullerenes: Cage-like structures, C₆₀ is buckminsterfullerene
- Organic compounds: Contain carbon-hydrogen bonds, lower melting points
- Inorganic compounds: Simple carbon compounds like CO, CO₂, carbonates
- Organic compounds: Generally insoluble in water, soluble in organic solvents
Common Mistakes to Avoid
Diamond and graphite are different elements, not different forms of the same element
Organic compounds are only those found in living organisms
Carbon has valency 2 because it needs 2 electrons to complete its octet
Memory Tips
Carbon's valency is 4 (tetravalent)
Catenation - Carbon's unique ability to form chains
Diamond's structure - 3D network of carbon atoms
Graphite's layered structure and conductivity
