Organic Chemistry

Key Points

  • Alkanes: CₙH₂ₙ₊₂ (saturated); Alkenes: CₙH₂ₙ (one double bond)
  • Alkanes undergo substitution; Alkenes undergo addition
  • Fermentation: C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
  • Esterification: acid + alcohol → ester + water (H₂SO₄ catalyst)
  • Addition polymers from alkenes (e.g. polyethene from ethene)
