Key Topics to Revise

1

Tetravalence of Carbon and Molecular Shapes

  • Carbon has unique property of catenation - ability to form covalent bonds with other carbon atoms
  • Carbon forms four covalent bonds due to its electronic configuration (1s² 2s² 2p²)
  • Three types of hybridization: sp³ (tetrahedral), sp² (trigonal planar), sp (linear)
2

Structural Representations and Molecular Models

  • Complete structural formulas show all atoms and bonds
  • Condensed formulas abbreviate by grouping atoms (CH₃CH₂OH)
  • Bond-line formulas show only carbon skeleton with zig-zag lines
3

Classification of Organic Compounds

  • Acyclic (open chain) compounds: straight or branched chains
  • Cyclic compounds: Alicyclic (non-aromatic rings) and Aromatic (benzene-like rings)
  • Functional groups determine chemical properties and reactions
4

IUPAC Nomenclature

  • IUPAC system provides systematic naming based on structure
  • Longest carbon chain determines the parent name
  • Number carbons to give substituents lowest possible numbers
