Q: What is in the A-Level Chemistry data booklet (SEAB 9476)?
A: The SEAB Chemistry data booklet contains the periodic table, important constants (R, F, L, Vm, Kw), ionisation energies, bond energies, standard electrode potentials, atomic and ionic radii, 1H NMR and IR reference ranges, aromatic directing effects, and qualitative analysis notes. It is provided as a clean copy in Papers 1-3 (not practicals). Below: official PDF download, quick-reference index, and Paper 1-3 exam tactics.
The official SEAB Chemistry Data Booklet (for H1 8873, H2 9476, H3 9813) is used in all written papers, except practicals (per the cover page of the SEAB PDF). Train with it early so your eyes know exactly where to look when seconds matter.
Note on syllabus codes: If you're searching for “9729 data booklet”, note that SEAB lists 9729 as an outgoing syllabus (marked “last year of exam in 2026”) while the 2026 Chemistry Data Booklet download is labelled 8873/9476/9813. Always verify against the official SEAB page.

“Explain a trend using numbers”
Ionisation energies; atomic and ionic radii
Support periodicity explanations with real values (e.g., IE1, radii).
“Estimate ΔH from bonds”
Bond energies
Use bonds broken − bonds formed. (If ΔHf∘/ΔHc∘ values are needed, they are typically provided in the question.)
“Determine feasibility / Ecell∘”
Standard electrode potentials
Build half-equations, compute Ecell∘, justify redox direction and cell notation.
“Identify an unknown from spectra”
1H NMR + IR reference ranges
Confirm functional groups, justify peaks, and avoid over-claiming a structure from one signal.
“Predict aromatic substitution products”
Orientating effects in aromatic substitution
Identify o/p vs m directing and activation/deactivation trends.
“Suggest tests / observations”
Qualitative analysis notes
Choose confirmatory reagents and state expected observations (don't guess colours).
Contents (Official Headings)
The SEAB Chemistry Data Booklet groups the tables under consistent headings. You don't need to memorise every value - you just need to know which heading to reach for:
Important values/constants: R=8.31J⋅K−1⋅mol−1, F=9.65×104C⋅mol−1, L=6.02×1023mol−1, Vm at s.t.p./r.t.p., Kw at 298K (plus a few physics constants like h and c).
Ionisation energies (1st-4th) for selected elements (for periodicity/trend explanations).
Bond energies (average bond enthalpies) for energetics estimates.
Standard electrode potentials at 298K for redox/electrochemistry.
Atomic/ionic radii for structure-property and periodicity discussions.
1H NMR chemical shift ranges (relative to TMS) and characteristic IR absorption frequencies.
Aromatic directing effects table (activating/deactivating; o/p vs m directing).
Qualitative analysis notes (confirmatory tests and observations).
Periodic table.
Your school's print may paginate slightly differently, but the content headings remain consistent across releases.
Exam Rules and Good Habits
You receive a clean Data Booklet with your paper; personal annotated copies are not permitted. Practise with an unmarked print.
Use the same edition for drills. Repeated exposure builds muscle memory for table layout and symbol conventions.
Write working that explicitly cites table lookups (e.g., “From Data Booklet: E∘ for AgX+/Ag=+0.80V”). This makes method credit obvious.
Keep significant figures consistent with given data. When in doubt, align to the precision in the table value you used.
High-Value Lookups You'll Use Often
Standard electrode potentials E∘ for constructing cells and judging feasibility.
Bond energies to estimate ΔH via bonds broken − bonds formed.
Ionisation energies and radii tables for trend explanations that need numbers, not vibes.
1H NMR and IR ranges to justify structure (especially when the prompt says “use evidence”).
Aromatic directing effects to predict major products and justify conditions.
Core constants and definitions (R, F, L, Vm; s.t.p./r.t.p.) so your units stay consistent.
Qualitative analysis notes (reagents and observations) for confirmatory tests.
Paper-Specific Tactics
Paper 2 (Structured)
Mark up the question first, then fetch constants in one pass to avoid bit-by-bit flipping.
When multiple tables could apply (e.g., bond enthalpy vs ΔHf∘), choose the one that minimises assumptions and state it.
The official SEAB cover page states the data booklet is not used for practical examinations. Keep your Paper 4 prep separate (planning + PDO + ACE), then use the booklet mainly to support Paper 1-3 work.
Micro-Formulas Worth Remembering by Heart
Optional enrichment (if taught / if provided): Nernst equation E=E∘−nFRTlnQ. For base-10 logs at 298K: E≈E∘−n0.0592log10Q. The 9476 syllabus expects qualitative concentration predictions; treat this as a tool, not a memorisation requirement.
Arrhenius: k=Ae−Ea/(RT). A two-point plot of lnk vs 1/T
Practise plugging numbers quickly with consistent units (e.g., keep energies in kJ⋅mol−1 or J⋅mol−1 throughout).
RTP vs STP (Which one does the question want?)
Many “data booklet” mistakes are not chemistry mistakes - they're conditions mistakes. Before you use Vm, R, or a standard value, check what the question specifies:
s.t.p. (as defined in the SEAB data booklet): 105Pa (1bar) and 273K, with Vm=22.7dm3⋅mol−1.
r.t.p. (as defined in the SEAB data booklet): 101325Pa (1atm) and 293K, with Vm=24dm3⋅mol−1
When in doubt, follow the conditions stated in the question stem and keep units consistent end-to-end (especially cm3 vs dm3).
Training Checklist
Print a clean, double-sided copy and place tabs only during home practice - not for the exam.
Build a personal “top 20” lookup list (constants and tables you reach for most) and rehearse timed retrieval.
Annotate typical pitfalls (sign conventions, base-10 vs natural log, SF/DP) in your notes, then practise on clean copies.
After each drill, note any value you hesitated on and add it to your flashcards.
FAQ
Where can I download the SEAB H2 Chemistry data booklet (9476) for 2026?
Use the official SEAB PDF link in the Download section above. It's labelled SEAB_Chemistry_Data_Booklet_8873_9476_9813.pdf and is the most reliable source to avoid outdated copies.
Is the chemistry data booklet provided during the A-Level exam? Can I bring my own copy?
You receive a clean booklet with the written paper. Personal annotated copies are not allowed in exams, so practise with an unmarked print (or a clean digital copy) to match exam conditions.
What if I'm searching for “9729 data booklet”?
Some older guides refer to H2 Chemistry as 9729. For 2026, SEAB lists 9729 as an outgoing syllabus (marked “last year of exam in 2026”), while the official chemistry data booklet download is labelled 8873/9476/9813 on the SEAB page.
Is this the “9476 data booklet” for H2 Chemistry?
Yes. The official SEAB download is labelled SEAB_Chemistry_Data_Booklet_8873_9476_9813.pdf, which includes the booklet used for H2 Chemistry (9476) written papers from 2026.
Is there an H2 Chemistry formula sheet / formula list provided in the exam?
SEAB provides a clean Chemistry data booklet (tables/constants/reference ranges) for the written papers, but it is not a full “formula sheet”. You still need to memorise key equations (and know when to use them). Start here: https://eclatinstitute.sg/blog/h2-chemistry-notes/H2-Chemistry-Formula-Sheet-2026
Which tables should I learn to find quickly for Paper 2 and Paper 3?
Electrode potentials, bond energies, ionisation energies/radii, and IR/1H NMR references are the fastest mark-unlockers. Aim for “one-pass flipping”: identify all lookups you'll need, then fetch them in one go before writing.
Does Paper 4 practical use the data booklet?
The SEAB cover page states the booklet is for written papers and excludes practicals. For Paper 4, train your practical planning and data processing separately, then use this booklet mainly to support your Paper 2/3 skills.
What is in the A-Level Chemistry data booklet?
The SEAB Chemistry data booklet contains the periodic table, important constants (R, F, L, Vm, Kw), ionisation energies, bond energies, standard electrode potentials, atomic/ionic radii, ¹H NMR and IR reference ranges, aromatic directing effects, and qualitative analysis notes. It is the same booklet for H1 (8873), H2 (9476), and H3 (9813) Chemistry.
Is the Chemistry data booklet the same for H1 and H2 Chemistry?
Yes - SEAB issues one Chemistry Data Booklet (labelled 8873/9476/9813) for all three Chemistry levels. The tables and constants inside are identical; the difference lies in which syllabus topics you are expected to apply them to.
Which constants must I memorise versus look up in the data booklet?
The data booklet provides R, F, L, Vm, and Kw - you do not need to memorise these values. However, you must memorise key equations (Hess's law cycles, pH/pOH definitions, rate law expressions) and know which table to consult for numerical inputs. The booklet supplies the numbers; you supply the method.
This guide helps you extract speed and certainty from the Data Booklet without memorising every number. Train with intention, cite your sources, and let the tables carry routine constants while you focus on explanation and method.
