Alcohols (Triple) – Lesson & Worksheet – Unit 4 – IGCSE Chemistry

Alcohols – Lesson & Worksheet – Unit 4 – IGCSE Chemistry
Structure, Formulae, Naming & Oxidation of Ethanol (Triple Only)

This Synapse Science resource introduces the alcohol homologous series, focusing on the −OH functional group, structural and displayed formulae, and the oxidation of ethanol under different conditions.

Students explore uses of alcohols, learn to draw and name methanol to butanol, and investigate oxidation through combustion, microbial processes, and potassium dichromate.

TOPICS COVERED – SPECIFICATION POINTS

• 4.29C: Know that alcohols contain the functional group −OH
• 4.30C: Understand how to draw structural and displayed formulae for methanol, ethanol, propanol and butanol and name each compound
• 4.31C: Know that ethanol can be oxidised by:
  • Burning in air or oxygen (complete combustion)
  • Reaction with oxygen in the air to form ethanoic acid (microbial oxidation)
  • Heating with potassium dichromate in dilute sulphuric acid to form ethanoic acid:contentReference[oaicite:0]{index=0}

WHAT’S INCLUDED

• Editable PowerPoint slides with diagrams, combustion examples and oxidation reactions
• Printable worksheet with scaffolded structural formula tasks and oxidation pathways
• Summary tables comparing oxidation methods and products
• Real-world applications of ethanol and vinegar production

KEY FEATURES

• Ideal for Paper 2 / Triple Science organic chemistry
• Visuals of microbial and chemical oxidation of ethanol
• Includes combustion reactions with word and symbol equations
• Matches Synapse Science layout for easy integration into Unit 4 series
