This comprehensive PowerPoint bundle covers IBDP Chemistry SL Topic 3.2: Functional Groups – Classification of Organic Compounds (first examination 2025), supporting students in building a strong foundation in organic chemistry. It is ideal for teaching, revision, and exam preparation, with clear explanations and structured progression across lessons.

Functional groups are specific groups of atoms within organic molecules that determine their chemical properties and reactions. This bundle helps students identify, classify, and apply their understanding of functional groups across different homologous series, while developing essential skills in representation, naming, and recognising isomerism.

The bundle includes six fully editable PowerPoint (.pptx) lessons, each designed to build on prior knowledge:
• Types of formula (molecular, structural, condensed, skeletal, stereochemical) and carbon’s catenation
• Functional groups and classification of organic compounds
• Homologous series, trends in physical properties and intermolecular forces
• IUPAC nomenclature of straight-chain organic compounds
• IUPAC nomenclature of branched-chain organic compounds
• Structural isomerism, including chain, position and functional group isomers

Each lesson includes:
• Retrieval starters (true/false) to activate prior knowledge
• Clear definitions of key terms and IB-specific language
• Step-by-step explanations and worked examples
• Visual representations of molecules and structures
• Mini whiteboard activities and practice questions with answers

The resource is carefully sequenced to support conceptual understanding, from basic representations of molecules through to more complex ideas such as isomerism and structure–property relationships. It is suitable for classroom teaching, independent study, or flipped learning.

File types included:
• 6 × Editable PowerPoint (.pptx) files

Last updated: 2026 – includes improved sequencing, additional examples, enhanced practice tasks, and clearer links to IB specification requirements for first examination 2025.
