IB DP Chemistry Resources-Practice Questions and Notes- 2026, 2027 & 2028 Syllabus
IB DP Chemistry Resources-Practice Questions and Notes
IB DP Chemistry 2025 Resources: Prepare for the IB exams with subject-specific practice questions, model answers, and comprehensive revision notes. All topics covered.
The new DP chemistry course was launched in February 2023 for first teaching in August 2023. First assessment will take place in May 2025. IBDP Chemistry courses are here as per new syllabus and guidelines provided by the board. Details of changes in pattern and syllabus are also mentioned on this page.

Changes in Syllabus for IBDP Chemistry First Assessment 2025
All students will only sit two external examinations
Paper 1A includes multiple-choice questions on the syllabus.
paper 1B includes data-based questions that are syllabus related. These papers provide an opportunity to assess some of the experimental skills and techniques.
Paper 2 includes short-answer and extended-response questions of intertwining skills, concepts and understandings placed into a suitable chemistry context.
Other changes include the removal of the option topics (materials, biochemistry, energy and medicinal chemistry). From these four options some of the content was incorporated into the course at either standard level or higher level.
Internal assessment
The ‘scientific investigation’ (internal assessment) will also see a change, with the opportunity for students to collaborate and support each other within small groups. Where appropriate, students will be able to share similar methodologies, provided that the independent or dependent variable differ, and the data collected is unique to each student.
Main take away from the changes in internal assessment are as below:
- Students will continue to submit an individual report with a maximum word count of 3,000 words.
- The revised criteria will place a greater emphasis on higher-order thinking skills
- 50% of the marks allocated for Conclusion and Evaluation.
Syllabus Framework for IBDP Chemistry First Assessment 2025
Skills in the study of chemistry | |
Structure Structure refers to the nature of matter from simple to more complex forms | Reactivity Reactivity refers to how and why chemical reactions occur |
Structure 1. Models of the particulate nature of matter | Reactivity 1. What drives chemical reactions? |
Structure 2. Models of bonding and structure | Reactivity 2. How much, how fast and how far? |
Structure 3. Classification of matter | Reactivity 3. What are the mechanisms of chemical change? |
The chemistry curriculum is built on two broad organizing concepts:
- Structure and
- Reactivity.
Each of these concepts is subdivided into topics and subtopics, which are all connected through the idea that structure determines reactivity, which in turn transforms structure.
IBDP Chemistry First Assessment 2025
| 2016 Syllabus (First assessment 2016) | 2025 Syllabus (First assessment 2025) |
|---|---|
| Core Topics (SL & HL) 1. Stoichiometric relationships 2. Atomic structure 3. Periodicity 4. Chemical bonding & structure 5. Energetics/thermochemistry 6. Chemical kinetics 7. Equilibrium 8. Acids & bases 9. Redox processes 10. Organic chemistry 11. Measurement & data processing | Core (integrated) Structure strand 1. Models of particulate nature of matter 2. Models of bonding & structure 3. Classification of matter Reactivity strand 1. What drives chemical reactions? 2. How much, how fast, how far? 3. Mechanisms of chemical change |
| Additional Higher Level (AHL) 12. Atomic structure 13. Periodic table – transition metals 14. Chemical bonding & structure 15. Energetics/thermochemistry 16. Chemical kinetics 17. Equilibrium 18. Acids & bases 19. Redox processes 20. Organic chemistry 21. Measurement & analysis | HL Content – Integrated into same Structure–Reactivity framework – More depth in enthalpy, entropy & spontaneity – Transition metals included under classification of matter & bonding – HL extensions merged into main strands (no separate numbering) |
| Options (SL/HL) A. Materials B. Biochemistry C. Energy D. Medicinal chemistry | No options in 2025 All students study a common syllabus (Structure & Reactivity). Old option themes (biochemistry, energy, medicinal) appear only as contexts, not examinable topics. |
| Measurement & skills Treated as stand-alone topics (Topic 11 & 21). | Measurement & skills Now integrated into “Skills in the study of chemistry” and the experimental programme (practical, investigation, collaborative project). |
