AQA AS Level Chemistry 2025 Paper 2 Question Paper

AQA AS Level Chemistry 2025 Paper 2 Question Paper Why It Stands Out: • Combines mechanistic organic chemistry with quantitative physical chemistry • Includes real lab setups, reaction mechanisms, and spectral analysis • Features multi-step calculations, IR interpretation, and mass spectrometry • Ideal for mock exams, revision bundles, and exam technique coaching • Matches the latest AQA specification (7404/2) with clear topic segmentation Topics Covered: • Halogenoalkanes: nucleophilic substitution, elimination, carbocation stability • Reaction mechanisms: hydration of alkenes, electrophilic addition, co-ordinate bonding • Intermolecular forces: hydrogen bonding, boiling point trends, polarity • Spectroscopy: IR absorption ranges, mass spectrometry, molecular formula deduction • Organic analysis: functional group isomerism, test-tube reactions, combustion equations • Physical chemistry: catalysts, temperature effects, Maxwell-Boltzmann distribution • Thermochemistry: enthalpy of combustion, bond enthalpy calculations • Experimental techniques: distillation setup, anti-bumping granules, safety protocols • Environmental chemistry: biofuels, carbon neutrality, catalytic converters • Multiple choice section: IUPAC naming, global warming gases, reaction equations
