This PowerPoint lesson covers mass spectrometry for IBDP Chemistry HL (first examination 2025), focusing on fragmentation patterns and how to deduce structural features from spectra. It provides a clear, step-by-step explanation of how mass spectrometry works and how students can interpret data in exam-style questions.

Mass spectrometry is an analytical technique used to identify compounds by ionising molecules and measuring the mass-to-charge ratio (m/z) of the resulting ions. By analysing the molecular ion peak and fragmentation pattern, students can determine molecular mass and infer structural features of organic compounds .

This fully editable PowerPoint (.pptx) is designed specifically for HL students and aligns with the IB Diploma Programme specification. The lesson begins with a retrieval starter activity before introducing key terminology such as molecular ions, cation fragments and fragmentation patterns. It then walks students through the five key stages of a mass spectrometer (vaporisation, ionisation, acceleration, deflection and detection), ensuring strong conceptual understanding .

The resource includes:
• Retrieval starter activity (true/false)
• Clear definitions of key terms
• Step-by-step explanation of how a mass spectrometer works
• Ionisation equations and formation of molecular ions
• Explanation of fragmentation and how spectra are produced
• Identification of molecular ion peak, base peak and M+1 peak
• Worked examples (including ethanoic acid fragmentation)
• Methods for calculating mass lost and identifying fragments
• Practice questions with answers for consolidation

This lesson is ideal for both teaching new content and revision, helping students confidently interpret mass spectra and apply their understanding in IB exam questions.

File type included:
• Editable PowerPoint (.pptx)

Last updated: 2026 – improved worked examples, added clearer step-by-step guidance for fragmentation calculations, and included additional exam-style practice questions aligned with IB HL assessment objectives.

BUNDLE S3.2 Functional Groups: Classification of Organic Compounds, SL & HL (IBDP Chemistry)

This bundle of PowerPoints covers S3.2 Functional groups: Classification of organic compounds for IBDP Chemistry (first examination 2025), including naming, isomerism and analytical techniques. It provides a complete, structured sequence of lessons to build students’ understanding of organic chemistry from foundational concepts through to HL analysis skills. Functional groups are specific groups of atoms within organic molecules that determine their chemical properties and reactions. By identifying functional groups, chemists can classify compounds, predict reactivity and systematically name molecules. This bundle supports students in developing these essential skills, progressing from basic formula types through to spectroscopy and structural determination. This fully editable bundle includes 12 PowerPoint (.pptx) lessons, carefully sequenced to support both SL and HL teaching. Early lessons focus on foundational knowledge such as types of formula, homologous series and nomenclature, before progressing into structural and stereoisomerism. The later lessons develop higher-level analytical skills, including mass spectrometry, IR spectroscopy, ¹H NMR and combining techniques to identify unknown compounds. The bundle includes: • Lesson 1: Types of Formula • Lesson 2: Functional Groups • Lesson 3: Homologous Series • Lesson 4–5: Nomenclature (straight-chain and branched-chain) • Lesson 6: Structural Isomerism • Lesson 7–8 (HL): Stereoisomerism (cis–trans and optical) • Lesson 9–12 (HL): Mass spectrometry, IR spectroscopy, ¹H NMR and combining analytical techniques Across the lessons, you will find: • Retrieval starter activities and clear key definitions • Step-by-step explanations and worked examples • Visual representations of structures and isomers • Links between structure, bonding and analytical data • Practice questions with answers for consolidation This bundle is ideal for teaching the full S3.2 topic or for structured revision, helping students build confidence in organic chemistry and prepare effectively for IB exam questions. File types included: • 12 editable PowerPoint (.pptx) files Last updated: 2026 – improved lesson sequencing, added HL analytical content, and enhanced practice questions aligned to IB assessment objectives.
