What the real CXC CAPE Chemistry paper looks like

Paper 01 (Multiple Choice)
45 multiple-choice questions, 1 mark each. About 1 hour 30 minutes. Tests knowledge across all three Modules of the Unit.
Paper 02 (Essay / Structured)
Extended essay and structured questions, one per Module. Around 2 hours 30 minutes. Tests developed argument, application and use of examples.
Paper 03 (Internal Assessment)
School-Based Assessment for school candidates (Paper 03/1) or an alternative written paper for private candidates (Paper 03/2). Coursework/research component worth a significant share of the Unit grade.
Total written exam time: ~4 hours across Paper 01 and Paper 02, plus the Internal Assessment.
Grading: Unit grades: I (highest) to VII (lowest), with a Grade Point Average and per-Module profile. Grades I–V are the pass range for most purposes.

Mini practice paper: 8 questions

Mixed-difficulty questions from across the Chemistry syllabus. Tap "Show answer" after each to check yourself.

Q1 · Difficulty 1/3

What is the monomer of PTFE, poly(tetrafluoroethene)?

  1. CH₂=CHF
  2. CF₃–CF₃
  3. CH₂=CF₂
  4. CF₂=CF₂
Show answer & explanation
✓ Answer: D — CF₂=CF₂
Award 1 mark. The monomer must have a C=C bond and four fluorine atoms. CF₃–CF₃ has no double bond and so cannot undergo addition polymerisation.
Q2 · Difficulty 1/3

What colour change is seen when acidified potassium dichromate(VI) oxidises an alcohol?

  1. Orange to green
  2. Green to orange
  3. Purple to colourless
  4. Colourless to orange
Show answer & explanation
✓ Answer: A — Orange to green
Award 1 mark. Orange Cr₂O₇²⁻ is reduced to green Cr³⁺. Purple to colourless is the change for acidified manganate(VII).
Q3 · Difficulty 1/3

What type of reaction does benzene typically undergo?

  1. Electrophilic substitution
  2. Electrophilic addition
  3. Nucleophilic substitution
  4. Free-radical addition
Show answer & explanation
✓ Answer: A — Electrophilic substitution
Award 1 mark. Substitution keeps the stable delocalised ring intact. Addition would destroy it, which costs a great deal of energy.
Q4 · Difficulty 1/3

Which test shows that a hydrocarbon is unsaturated?

  1. It turns limewater milky
  2. It turns damp red litmus blue
  3. It gives a squeaky pop with a lighted splint
  4. It decolourises orange bromine water
Show answer & explanation
✓ Answer: D — It decolourises orange bromine water
Award 1 mark. Bromine adds across the C=C bond, so the orange colour disappears. Limewater tests for CO₂ and the squeaky pop is the test for hydrogen.
Q5 · Difficulty 1/3

Which gas is given off when sodium reacts with ethanol?

  1. Oxygen
  2. Hydrogen
  3. Carbon dioxide
  4. Ethene
Show answer & explanation
✓ Answer: B — Hydrogen
Award 1 mark. 2CH₃CH₂OH + 2Na → 2CH₃CH₂ONa + H₂. The reaction is like sodium with water but much gentler. The other options (Oxygen; Carbon dioxide; and Ethene) do not fit.
Q6 · Difficulty 1/3

What is the standard electrode potential of the standard hydrogen electrode?

  1. 1.00 V
  2. −1.00 V
  3. 0.00 V
  4. +0.76 V
Show answer & explanation
✓ Answer: C — 0.00 V
00 V. Award 1 mark. The hydrogen electrode is the reference against which all other E° values are measured, so it is defined as exactly 0.00 V.
Q7 · Difficulty 1/3

What is the name of C₆H₅CH₃?

  1. Methylcyclohexane
  2. Methylbenzene
  3. Ethylbenzene
  4. Phenylamine
Show answer & explanation
✓ Answer: B — Methylbenzene
Award 1 mark. It is a benzene ring with one methyl group. Methylcyclohexane is C₆H₁₁CH₃, with a saturated ring.
Q8 · Difficulty 1/3

Which alcohol is made by the fermentation of sugars and is present in alcoholic drinks?

  1. Methanol
  2. Ethanol
  3. Propan-1-ol
  4. Propane-1,2,3-triol
Show answer & explanation
✓ Answer: B — Ethanol
Award 1 mark. Yeast enzymes convert glucose to ethanol and CO₂. In the Caribbean, molasses from sugar cane is fermented to make rum.
