Formula sheet
The card below opens today's A-level Chemistry paper with this sheet in the drawer, so you practise the way you will sit the exam. The contents follow in our own layout and words. Check against CCEA's Chemistry Data Sheet before you rely on anything here.
A-level Chemistry: Year 1
General information
Also: 1 tonne = 10⁶ g; 1 metre = 10⁹ nm.
| Quantity | Symbol | Value | Unit |
|---|---|---|---|
| one mole of any gas at 293 K and 1 atmosphere (10⁵ Pa) occupies | V_m | 24 | dm³ |
| Avogadro constant | NA | 6.02 × 10²³ | mol⁻¹ |
| Planck constant | h | 6.63 × 10⁻³⁴ | J s |
| specific heat capacity of water | c | 4.2 | J g⁻¹ K⁻¹ |
| speed of light | c | 3 × 10⁸ | m s⁻¹ |
Characteristic absorptions in infrared spectroscopy
Wavenumbers are in cm⁻¹.
| Wavenumber / cm⁻¹ | Bond | Compound |
|---|---|---|
| 550-850 | C-X (X = Cl, Br, I) | Haloalkanes |
| 750-1100 | C-C | Alkanes, alkyl groups |
| 1000-1300 | C-O | Alcohols, esters, carboxylic acids |
| 1450-1650 | C=C | Arenes |
| 1600-1700 | C=C | Alkenes |
| 1650-1800 | C=O | Carboxylic acids, esters, aldehydes, ketones, amides, acyl chlorides |
| 2200-2300 | C≡N | Nitriles |
| 2500-3200 | O-H | Carboxylic acids |
| 2750-2850 | C-H | Aldehydes |
| 2850-3000 | C-H | Alkanes, alkyl groups, alkenes, arenes |
| 3200-3600 | O-H | Alcohols |
| 3300-3500 | N-H | Amines, amides |
Proton chemical shifts in NMR spectroscopy
Relative to TMS. These shifts depend on concentration and temperature and may fall outside the ranges.
| Shift / ppm | Structure | Type |
|---|---|---|
| 0.5-2.0 | -CH | Saturated alkanes |
| 0.5-5.5 | -OH | Alcohols |
| 1.0-3.0 | -NH | Amines |
| 2.0-3.0 | -CO-CH, -N-CH, C₆H₅-CH | Ketones, amines, arenes (aliphatic on ring) |
| 2.0-4.0 | X-CH | X = Cl or Br (3.0-4.0), X = I (2.0-3.0) |
| 4.5-6.0 | -C=CH | Alkenes |
| 5.5-8.5 | RCONH | Amides |
| 6.0-8.0 | C₆H₅ | Arenes (on ring) |
| 9.0-10.0 | -CHO | Aldehydes |
| 10.0-12.0 | -COOH | Carboxylic acids |
What the CCEA sheet leaves out
- No carbon-13 NMR table. Only proton shifts are given.
- No electrode potentials and no ionic product of water.
- No gas constant. The only gas figure is 24 dm³ per mole at 293 K and 1 atmosphere.
No notes, no other booklet
CCEA states that copies must be free from notes or additions of any kind and that no other data booklet is authorised. Your clean copy is all you get.
Its infrared table is arranged by wavenumber first, with the bond and the compound beside it, and its proton NMR table lists shifts such as 9.0 to 10.0 for an aldehyde and 10.0 to 12.0 for a carboxylic acid.
Work out the relative atomic mass of an element from its isotopes and their abundances.

Worked example: heating water with the CCEA value
How much energy warms 100 g of water by 5.0 K? CCEA gives c = 4.2 J g⁻¹ K⁻¹.
Other boards give 4.18, which would produce 2090 J. Use the number on your sheet.
The CCEA sheet and the other boards
| Board | Sheet | What it holds |
|---|---|---|
| AQA | A-level Chemistry Data Booklet (7405), June 2023 series insert | Periodic table, an element list, three data tables (A infrared, B proton NMR, C carbon-13 NMR) and tables for phosphate and sugars, bases and amino acids; no table of constants |
| Edexcel | Data Booklet (9CH0), Issue 2, Summer 2017 | Physical constants, infrared, NMR, Pauling electronegativities, standard electrode potentials and the periodic table |
| OCR A | Data Sheet for Chemistry A (H032, H432), 4 pages | General information including the Arrhenius equation, infrared, NMR charts and the periodic table |
| Eduqas | GCE AS/A level Chemistry Data Booklet (B410U10-1A) | Constants and conversions, infrared, carbon-13 and proton NMR, and the periodic table |
| WJEC | GCE AS/A level Chemistry Data Booklet | The same opening constants as Eduqas, then infrared, NMR and the periodic table |
| CCEA (this guide) | Chemistry Data Sheet, GCE A/AS examinations (subject code 1110) | General information, infrared and proton NMR tables, and the periodic table |
CCEA gives c as 4.2 where OCR, Eduqas and WJEC give 4.18, and it uses 293 K for the molar gas volume. It is the only sheet here without a carbon-13 table.
Exam answers
Our daily paper answers appear after marking and are our own, not CCEA's.
Daily papers for CCEA chemists
Use Chemistry 1 and Chemistry 2 as short, timed checks. Practise reading proton shifts quickly, since carbon-13 is not on your sheet.
CCEA sheet slips
- Looking for carbon-13 data.
- Using the gas volume at the wrong temperature.
- Writing on the sheet.
