Key Topics to Revise

1

Bonding in Carbon - Covalent Bonding

  • Carbon has atomic number 6 with electronic configuration 2,4 - it has 4 valence electrons
  • Carbon cannot easily gain or lose 4 electrons to form ions due to high energy requirements
  • Carbon forms covalent bonds by sharing electrons with other atoms
2

Versatile Nature of Carbon

  • Catenation: Carbon's unique ability to form bonds with other carbon atoms forming chains, rings, and branches
  • Carbon forms millions of compounds - more than all other elements combined
  • Saturated compounds: Only single bonds between carbon atoms (alkanes)
3

Nomenclature of Carbon Compounds

  • IUPAC naming system based on longest carbon chain
  • Identify number of carbon atoms: meth(1), eth(2), prop(3), but(4), pent(5), hex(6)
  • Add prefixes for functional groups (chloro-, bromo-) or suffixes (-ol, -al, -one, -oic acid)
4

Chemical Properties of Carbon Compounds

  • Combustion: Carbon compounds burn in oxygen to produce CO₂, H₂O, heat and light
  • Complete combustion gives clean blue flame; incomplete combustion gives yellow sooty flame
  • Saturated hydrocarbons give cleaner flames than unsaturated ones
