🔍 OCR Chemistry A H432/02 2026: What Is Paper 2?
OCR A Level Chemistry A H432/02 is the Synthesis and Analytical Techniques paper. It is heavily focused on organic chemistry, mechanisms, synthesis routes, spectroscopy, chromatography, carbonyl chemistry, acids, polymers and practical analytical methods.
This paper can be difficult because questions often combine several skills. A single question may ask students to interpret data, identify a compound, explain a reaction mechanism, choose reagents and justify a synthetic route.
Students searching for OCR Chemistry A H432/02 predictions, OCR Chemistry Paper 2 predicted topics or OCR A Level Chemistry A Paper 2 predictions usually want to know which areas are most likely to be valuable for final revision.
The safest approach is always to revise the full specification. However, using a Paper 2 predicted paper helps students practise the most exam-relevant skills under timed conditions.
🧪 OCR Chemistry A H432/02 Predicted Topics for 2026
Based on the structure of this OCR A Level Chemistry A H432/02 2026 predicted paper, students should pay particular attention to the following predicted topic areas.
1. Multiple Choice Foundations for Paper 2
OCR Paper 2 begins with multiple choice questions. These are short, but they can test a very wide range of chemistry. Students should revise the common foundation topics that can appear quickly at the start of the paper.
Important areas include:
Isotopes and subatomic particles
Water of crystallisation calculations
Ionic bonding and lattice strength
Bond angles and lone pair repulsion
Free radical substitution
Intermolecular forces and boiling points
Weak acids such as phenol
Carbonyl tests and oxidation
Amino acids and optical isomerism
2,4-DNPH and Tollens’ reagent
Combustion and molecular formula calculations
Proton NMR splitting patterns
TLC and Rf values
These questions are useful for predictions because they test small but high-value details. A few marks can be lost quickly if students overlook definitions, reagents or conditions.
2. Alkenes, E/Z Isomerism and Electrophilic Addition
Alkenes are a strong predicted topic for OCR Chemistry A H432/02. Students should be comfortable with stereoisomerism, addition reactions and mechanisms.
Key areas to revise include:
E/Z isomerism
Cahn–Ingold–Prelog priority rules
Maleic acid and fumaric acid
Hydration of alkenes with steam
Phosphoric acid catalyst
Electrophilic addition mechanisms
Curly arrows and carbocation intermediates
Markovnikov’s rule
Carbocation stability
Students often lose marks in mechanisms because curly arrows start from the wrong place, dipoles are not shown, or the carbocation intermediate is drawn incorrectly. A good OCR Chemistry Paper 2 predicted paper should give students realistic practice with these common exam traps.
3. Esters, Oxidation and Synthetic Routes
Esters and organic synthesis are major Paper 2 areas. Students need to understand how compounds can be converted from one functional group to another and why some synthetic routes work better than others.
Students should revise:
Ester functional groups
Oxidation of primary alcohols
Oxidation of secondary alcohols
Carboxylic acid formation
Why ketones do not form esters directly with alcohols
Distillation versus reflux
Purity testing using melting point
Industrial synthesis, yield and cost
This is a strong area for OCR A Level Chemistry A Paper 2 predictions because it tests both reaction knowledge and decision-making. Students must explain why a route works, not just memorise reagents.
4. Aromatic Chemistry and Directing Groups
Aromatic chemistry is one of the most important topics for OCR A Level Chemistry A Paper 2. It can test mechanisms, electrophile formation, catalysts and directing effects.
Key areas include:
Nitration of benzene
Formation of the nitronium ion
Electrophilic substitution mechanisms
Unstable intermediates in benzene reactions
Regeneration of the sulfuric acid catalyst
Bromination of nitrobenzene
Halogen carrier catalysts
Phenol reactivity compared with benzene
2-directing, 4-directing and 3-directing groups
This topic is particularly important because students must evaluate synthetic routes. For example, nitrating first and brominating second may give a different major product from brominating first and nitrating second.
5. Carbonyl Chemistry: Aldehydes, Ketones and Nucleophilic Addition
Carbonyl chemistry is another high-value Paper 2 topic. Students should be able to distinguish aldehydes and ketones, explain nucleophilic addition and describe reactions with reducing agents and HCN.
Important revision areas include:
Butanal and pentan-2-one reactions
Acidified potassium dichromate(VI)
Orange to green colour change for aldehydes
Ketones not oxidised under these conditions
NaBH4 reduction
Hydride ion as a nucleophile
Bond polarity in C=O
HCN addition using NaCN and H2SO4
Hydroxynitrile formation
Increasing carbon chain length in synthesis
Students often lose marks because they describe the reagent but not the observation, or they identify the nucleophile without explaining why it attacks the carbonyl carbon.
6. Proton NMR and Structure Deduction
Proton NMR is one of the clearest Paper 2 predicted topics because it tests analysis rather than simple recall. Students need to use splitting patterns, chemical shifts and integration ratios together.
Students should revise:
The n+1 rule
Singlet, triplet and quartet patterns
Relative peak areas
Chemical shift values
Identifying proton environments
Deducing structures from C4H8O2 data
Drawing full structural formulae
This is a strong OCR Chemistry H432/02 predicted topic because it often appears as a longer 6-mark style question. Students should practise writing a logical explanation, not just naming the compound.
7. IR Spectroscopy, Mass Spectrometry and Elemental Analysis
IR and mass spectrometry are central to Synthesis and Analytical Techniques. These questions often require students to combine multiple pieces of evidence to identify an unknown compound.
Students should revise:
Stretching and bending vibrations in IR
Factors affecting IR absorption wavenumber
Bond strength and atomic mass
Elemental analysis calculations
Empirical formula and molecular formula
Molecular ion peaks
Carboxylic acid IR absorptions
Ester IR absorptions
Fragment ions and m/z values
Fingerprint region below 1500 cm⁻¹
This is an important predicted topic because OCR can combine calculation, graph interpretation and functional group identification in one question.
8. Redox Titration and Practical Calculations
Redox titration is a strong Paper 2 prediction because it tests practical chemistry, stoichiometry and concentration calculations.
Students should revise:
Sodium ethanedioate as a primary standard
Potassium manganate(VII) titrations
Mole calculations from mass
Concentration calculations
Stoichiometric ratios in redox equations
Determining iron content in tablets
Percentage by mass calculations
Many students make mistakes in titration questions by using the wrong mole ratio or not converting cm³ into dm³. A predicted paper is useful because it forces students to practise the full calculation sequence under timed conditions.
9. Polyamides, Nylon-6,6 and Amino Acids
Polymers and amino acids can appear as both short questions and extended response questions. This makes them a useful target for OCR Chemistry A Paper 2 predictions.
Students should revise:
Nylon-6,6 repeat units
Amide bonds
Condensation polymerisation
Water loss versus HCl loss
Using acyl chlorides in polymerisation
Aspartic acid structure
Chiral centres and optical isomerism
Ester formation with ethanol
Polyamide hydrolysis in hot aqueous sodium hydroxide
This is a good Higher-level topic because it tests evaluation. Students may need to assess whether a statement is fully correct, partly correct or chemically inaccurate.
