This PowerPoint lesson covers combining analytical techniques for IBDP Chemistry HL (first examination 2025), helping students determine unknown organic structures using multiple spectra. It provides a clear, step-by-step approach to interpreting and integrating data from mass spectrometry, infrared (IR) spectroscopy and ¹H NMR.

Combining analytical techniques involves using different experimental methods together to identify the structure of a compound. While each technique provides partial information, combining mass spectrometry (molecular mass and fragments), IR spectroscopy (functional groups), and ¹H NMR (proton environments) allows chemists to confidently deduce full molecular structures. This skill is essential for IB HL students and frequently assessed in exam questions.

This fully editable PowerPoint (.pptx) is designed for HL teaching and revision. The lesson begins with a retrieval starter reviewing NMR concepts before building a structured method for analysing unknown compounds. Students are guided through a complete worked example, showing how to combine evidence from all three techniques to identify a compound such as propanoic acid.

The resource includes:
• Retrieval starter activity linking prior spectroscopy knowledge
• Clear definitions of key analytical techniques (mass spectrometry, IR, ¹H NMR)
• Explanation of how each technique contributes different information
• Step-by-step method for identifying unknown compounds
• Interpretation of molecular ion peaks and fragmentation patterns
• Identification of functional groups using IR spectra
• Analysis of chemical shifts, integration and splitting patterns in ¹H NMR
• Fully worked example combining all three techniques
• Emphasis on exam technique and logical reasoning
• Practice questions with answers for consolidation

This lesson is ideal for developing high-level analytical and problem-solving skills, preparing students for IB exam questions that require interpreting multiple data sources to determine molecular structure.

• Editable PowerPoint (.pptx)

Last updated: 2026 – enhanced worked example clarity, added structured problem-solving steps, and improved exam-style practice questions aligned to 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.
