Organic Chemistry, Metals and Analysis
Integrate carbon chemistry, polymers, metal reactivity, particle theory, chemical tests and air and water chemistry.
How to prepare for the current ESAT
Confirm your course combination, build no-calculator fluency from Mathematics 1 upward, and use official Pearson materials for authentic timing and interface rehearsal.
Core concepts
Concept 1
Recognise and name specified organic families, reactions, isomers, polymers and combustion products.
Exam cue: Locate the functional group before naming or predicting a reaction.
Concept 2
Relate metal extraction, displacement, uses and transition-metal behaviour to reactivity and properties.
Exam cue: Place a metal in the reactivity series before selecting extraction or displacement.
Concept 3
Use particle models and qualitative tests to identify states, gases, ions and water and evaluate air or water chemistry.
Exam cue: Match the observation exactly to the specified analytical test.
Risk pitfalls and guardrails
Confusing addition and condensation polymerisation.
Guardrail: Do not use calculator-dependent shortcuts, import a fact outside the annual specification or overlook a unit, sign, scale or course-module boundary.
Predicting extraction independent of metal reactivity.
Guardrail: Do not use calculator-dependent shortcuts, import a fact outside the annual specification or overlook a unit, sign, scale or course-module boundary.
Naming an ion from reagent alone without the required observation.
Guardrail: Do not use calculator-dependent shortcuts, import a fact outside the annual specification or overlook a unit, sign, scale or course-module boundary.
Memory anchors
Homologous series
Same functional group and general formula with systematic trends.
Alkene test
Bromine water is decolourised by a carbon–carbon double bond.
Addition polymer
Double bonds open and monomers join without a small molecule leaving.
Metal extraction
More reactive metals require stronger reduction methods.
Particle model
State properties follow spacing, motion and attraction.
Test evidence
Reagent plus observation identifies the substance.
Checkpoint rule
Do the check-up only after you can summarize each concept in one sentence and identify one dangerous pitfall from memory.
