Key Topics to Revise

1

IUPAC Nomenclature of Alkanes

  • IUPAC (International Union of Pure and Applied Chemistry) provides standardized naming rules for organic compounds
  • For straight-chain alkanes: Use word root + 'ane' (methane, ethane, propane, butane, pentane, hexane, heptane, octane, nonane, decane)
  • For branched alkanes: Identify longest carbon chain as main chain, number carbons to give branches lowest numbers
2

Nomenclature of Unsaturated Hydrocarbons

  • Alkenes contain C=C double bond with general formula CₙH₂ₙ
  • Alkenes naming: Word root + position of double bond + 'ene'
  • Alkynes contain C≡C triple bond with general formula CₙH₂ₙ₋₂
3

Functional Groups and Their Nomenclature

  • Functional groups are atoms/groups that determine chemical properties of organic compounds
  • Alcohols (-OH): Replace 'e' of alkane with 'ol' (methanol, ethanol)
  • Aldehydes (-CHO): Replace 'e' of alkane with 'al' (methanal, ethanal)
4

Aromatic Compounds

  • Benzene (C₆H₆) is the parent aromatic compound with hexagonal ring structure
  • Aromatic compounds contain benzene ring with delocalized π electrons
  • Benzene derivatives: phenol (C₆H₅-OH), benzoic acid (C₆H₅-COOH)
