Making Alcohols – Lesson & Worksheet – Unit 4 – IGCSE Chemistry
Ethanol Production by Fermentation & Ethene + Steam (Triple Only)

This Synapse Science resource explains how ethanol is manufactured by two key methods:

  1. Reacting ethene with steam in the presence of a phosphoric acid catalyst, and
  2. Fermenting glucose using yeast in anaerobic conditions.

Students compare these two processes, write chemical equations, and explore the conditions required for fermentation to work efficiently.

TOPICS COVERED – SPECIFICATION POINTS

  • 4.32C: Know that ethanol can be manufactured by:
    • Reacting ethene with steam in the presence of a phosphoric acid catalyst
    • Fermenting glucose using yeast, in the absence of air and at optimum temperature
  • 4.33C: Understand the reasons for fermentation, in the absence of air and at an optimum temperature:contentReference[oaicite:0]{index=0}

WHAT’S INCLUDED

  • Editable PowerPoint lesson with theory, reaction equations, and visual comparisons
  • Student worksheet with balanced equations, fermentation questions, and analysis
  • Comparison chart for industry vs fermentation method
  • Real-world application of ethanol as a fuel and solvent

KEY FEATURES

  • Ideal for Triple Science (Paper 2) students
  • Explains anaerobic conditions and enzyme temperature sensitivity
  • Balanced chemical equations: C₂H₄ + H₂O → C₂H₅OH and C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂
  • Clean Synapse Science layout — ready for printing, classwork, or homework
