Carboxylic Acids (Triple) – Lesson & Worksheet – Unit 4 – IGCSE Chemistry

Carboxylic Acids – Lesson & Worksheet – Unit 4 – IGCSE Chemistry
Structure, Naming, and Reactions with Metals & Carbonates (Triple Only)

This Synapse Science resource introduces the carboxylic acid homologous series and the –COOH functional group, as part of Edexcel IGCSE Chemistry (Triple). Students learn to name and draw the structural and displayed formulae of methanoic, ethanoic, propanoic, and butanoic acids. The lesson also covers their reactions with metals and carbonates, forming salts and gas.

TOPICS COVERED – SPECIFICATION POINTS

• 4.34C: Know that carboxylic acids contain the functional group –COOH
• 4.35C: Understand how to draw structural and displayed formulae for unbranched-chain carboxylic acids with up to four carbon atoms in the molecule, and name each compound
• 4.36C: Describe the reactions of aqueous solutions of carboxylic acids with metals and metal carbonates:contentReference[oaicite:0]{index=0}

WHAT’S INCLUDED

• Editable PowerPoint slides with theory, examples, equations, and reaction visuals
• Printable worksheet with naming and formula tasks, plus reaction equations
• Word and symbol equations for both metal and carbonate reactions
• Examples:
  • Magnesium + ethanoic acid → magnesium ethanoate + H₂
  • Propanoic acid + potassium carbonate → potassium propanoate + H₂O + CO₂

KEY FEATURES

• Triple Science (Paper 2) focused content
• Scaffolded drawing and equation tasks
• Reinforces acid reaction knowledge with organic acids
• Clean, structured Synapse Science layout for clarity and ease of use
