- Embedded changes notice, PDF page 97 · Version 1, September 2022. The printed notice says reagents in '15.1(c)' and '16.2(b)' were updated. The current content actually places the relevant alcohol-substitution list in 16.1.2(b) (PDF 35) and halogenoalkane production in 15.1.1(c) (PDF 34); the notice's shorthand was not invented as a new outcome code. · checked 2026-10-24

Remaining academic requirements
- Conceptual English-only alignment and independent AI content checks, not official Cambridge certification or teacher approval. A qualified teacher must check marking, level, route and teaching adequacy.
- Inventory limitation: all numbered theoretical subsections were located/read, but this is NOT an exhaustive leaf-outcome inventory. Individual numbered outcomes, lettered clauses, example lists and all practical bullets still need a teacher-checked leaf ledger.
- All listed Paper 3 apparatus/measurement/observation requirements and actual extended Paper 5 experimental planning remain practical training gaps. A numerical calculation, supplied observation or short design discussion does not demonstrate laboratory handling, microscopy drawing, data collection, a complete safe method or practical competence. No hazardous real-laboratory instructions are supplied by the additions.
- New questions are original English-only selected practice with indicative distinct marking points. Independent AI checking does not establish teacher approval, validated translations or full outcome teaching coverage. Arabic practice and bilingual academic verification are not supplied here.
- Subsections with no placed existing or new question at all: 1.2 (Isotopic properties; PDF 16); 3.1 (Electronegativity and bond type; PDF 19); 3.2 (Ionic attraction; PDF 19); 3.3 (Metallic bonding; PDF 20); 3.7 (Bonding electron diagrams; PDF 22); 9.1 (Period-three physical trends; PDF 26); 9.3 (Periodicity-based predictions; PDF 26); 11.2 (Halogens and hydrogen halides; PDF 27); 11.4 (Chlorine disproportionation and water; PDF 28); 13.1 (Aliphatic formulae and nomenclature; PDF 31); 13.3 (Organic geometry and hybridisation; PDF 32); 19.1 (Primary amine synthesis; PDF 37); 19.2 (Nitriles and hydroxynitriles; PDF 37); 21.1 (AS multistep organic routes; PDF 38); 23.3 (Entropy changes; PDF 40); 28.5 (Complex stability equilibria; PDF 46); 29.1 (A-level organic structures and names; PDF 48); 29.2 (Aromatic and acyl mechanisms; PDF 48); 32.1 (Alcohol acylation; PDF 50); 33.1 (Aromatic and substituted acids; PDF 50); 33.2 (Esters from acyl chlorides; PDF 51); 33.3 (Acyl substitution and hydrolysis; PDF 51); 36.1 (A-level multistep synthesis; PDF 53); 37.3 (Carbon-13 spectra; PDF 54). Even the other subsections have only selected question presence, not complete teaching/assessment coverage.
- Residual theory includes dot-and-cross/orbital sketches, full Period-3 chloride chemistry, halogen/hydrogen-halide redox and chlorine disproportionation, all named functional-group preparations, free-radical chains, carbonyl addition, multistep synthetic route breadth, detailed transition-metal reactions/complex stability, carbon-13 NMR and every nested specified example.
- Electrochemical salt-bridge explanations are useful supporting context but the bridge is not explicitly named as a standalone outcome; practical cell construction still needs teacher verification. Idealised corrosion-rate discussion does not establish a dedicated corrosion unit. All real titrations, gas collection, thermometry and qualitative identification remain supervised practical requirements.
- Cambridge 5.1.3 uses 298 K and 101 kPa for its stated standard conditions; do not silently replace that convention with a generic 100 kPa board convention. Nernst examples here use the supplied 298 K relation and unit solid activities, not unrestricted concentrated-solution accuracy.
