Question 1 · 1 mark · Difficulty 1/3

Which of the following monomers undergoes addition polymerisation to form poly(propene)?

  1. CH3CH2CH3
  2. CH2=CHCH3
  3. HOOC–COOH
  4. CH2=CH2
Show answer & explanation
✓ Answer: BCH2=CHCH3
Propene (CH2=CHCH3) contains a C=C double bond and undergoes addition polymerisation to form poly(propene). Option B is ethene, which forms poly(ethene). Option C is propane, a saturated alkane with no double bond and cannot polymerise. Option D is a dicarboxylic acid used in condensation polymerisation, not addition polymerisation.
Question 2 · 1 mark · Difficulty 1/3

What type of small molecule is released as a by-product during condensation polymerisation?

  1. Water or hydrogen chloride
  2. Nitrogen or ammonia
  3. Hydrogen or methane
  4. Carbon dioxide or oxygen
Show answer & explanation
✓ Answer: AWater or hydrogen chloride
Condensation polymerisation releases a small molecule — commonly water (H2O) or hydrogen chloride (HCl) — each time two monomers join. Carbon dioxide, oxygen, nitrogen, ammonia, hydrogen, and methane are not produced in condensation polymerisation reactions studied at IGCSE. These distractors reflect common confusion with other reaction types.

CIE IGCSE Chemistry: Polymers: addition and condensation polymerisation FAQ

How many CIE IGCSE Chemistry questions on Polymers: addition and condensation polymerisation are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Polymers: addition and condensation polymerisation for CIE IGCSE Chemistry, with new questions added every week. Each question gives you instant feedback and a full examiner-style mark scheme that tells you exactly what would earn marks on a real CIE paper. The questions span the full difficulty range — from straightforward recall (level 1) right up to multi-step reasoning and evaluation (level 3) — so the bank works for first-pass revision and final exam-week stress testing alike.
Is Kramizo free for CIE IGCSE students preparing for Chemistry?
Yes — completely free. Every student gets 45 questions a day on the free plan, with no card required and no trial countdown. That free quota works across every subject and every topic in our bank, so you can mix Polymers: addition and condensation polymerisation practice with other Chemistry topics or even switch to a totally different CIE subject without paying anything. Kramizo's optional Pro plan removes the daily cap and adds detailed progress analytics, but the free tier is the real product — used by thousands of GCSE, IGCSE and CSEC students.
Are the Polymers: addition and condensation polymerisation questions aligned to the official CIE IGCSE Chemistry syllabus?
Every question is written against the published CIE IGCSE Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CIE paper. Explanations are written in the style of official examiner mark schemes — they tell you what is being awarded marks and why distractors are wrong, not just whether you got it right. The bank is continually refined to match the latest syllabus updates from CIE.
How is Polymers: addition and condensation polymerisation typically tested on CIE IGCSE Chemistry papers?
Polymers: addition and condensation polymerisation appears across multiple question types on real CIE IGCSE Chemistry papers — most commonly as multiple-choice questions in the objective section, structured short-answer questions in the main paper, and occasionally as part of an extended response. Kramizo's practice bank reflects that mix: 4-option MCQs, true/false statements, fill-in-the-blank key terms, multi-select questions, and ordering questions. Working through the bank gives you exposure to every question style examiners actually use.
