Question 1 · 1 mark · Difficulty 1/3

Which structural formula correctly represents propan-1-ol?

  1. CH₃CH₂CH₂OH
  2. CH₃CH(OH)CH₃
  3. CH₃CH₂CHO
  4. CH₃CH₂COOH
Show answer & explanation
✓ Answer: ACH₃CH₂CH₂OH
Award 1 mark for CH₃CH₂CH₂OH. Propan-1-ol has a three-carbon chain with the hydroxyl group on the first (terminal) carbon. B is incorrect because it shows propan-2-ol (hydroxyl on the middle carbon). C is incorrect because it shows propanal (an aldehyde, not an alcohol). D is incorrect because it shows propanoic acid (a carboxylic acid).
Question 2 · 1 mark · Difficulty 1/3

Ethanol can be produced by fermentation of glucose using yeast. Which conditions are required for this process?

  1. Temperature above 50°C and presence of oxygen
  2. Temperature between 25–37°C and absence of oxygen
  3. Temperature below 10°C and presence of oxygen
  4. Temperature between 25–37°C and presence of oxygen
Show answer & explanation
✓ Answer: BTemperature between 25–37°C and absence of oxygen
Award 1 mark for identifying that fermentation requires optimum enzyme temperature (25–37°C) and anaerobic conditions. A is incorrect because temperatures above 50°C denature the enzymes in yeast. C is incorrect because low temperatures slow enzyme activity too much for effective fermentation. D is incorrect because oxygen causes yeast to respire aerobically, producing carbon dioxide and water instead of ethanol.

CIE IGCSE Chemistry: Alcohols — structure, properties and reactions (fermentation, oxidation, uses) FAQ

How many CIE IGCSE Chemistry questions on Alcohols — structure, properties and reactions (fermentation, oxidation, uses) are there on Kramizo?
Kramizo currently has 20 exam-board-aligned practice questions on Alcohols — structure, properties and reactions (fermentation, oxidation, uses) 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 Alcohols — structure, properties and reactions (fermentation, oxidation, uses) 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 Alcohols — structure, properties and reactions (fermentation, oxidation, uses) 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 Alcohols — structure, properties and reactions (fermentation, oxidation, uses) typically tested on CIE IGCSE Chemistry papers?
Alcohols — structure, properties and reactions (fermentation, oxidation, uses) 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.
