Question 1 · 1 mark · Difficulty 1/3

What products are formed from the complete combustion of a hydrocarbon?

  1. Carbon dioxide and water
  2. Carbon monoxide and hydrogen
  3. Soot and steam
  4. Carbon and water
Show answer & explanation
✓ Answer: A — Carbon dioxide and water
Complete combustion (plenty of oxygen): hydrocarbon + O₂ → CO₂ + H₂O. Incomplete combustion produces carbon monoxide and/or soot.
Question 2 · 1 mark · Difficulty 1/3

Ethene reacts with hydrogen gas in the presence of a nickel catalyst. What is the product of this reaction?

  1. Ethanol
  2. Methane
  3. Ethane
  4. Propane
Show answer & explanation
✓ Answer: C — Ethane
When ethene (CH₂=CH₂) undergoes hydrogenation with H₂ and a nickel catalyst, hydrogen adds across the double bond to form ethane (CH₃CH₃). This is an addition reaction. The catalyst lowers the activation energy but is not consumed in the reaction.

CXC CSEC Chemistry: Organic Chemistry FAQ

Is Kramizo free for CXC CSEC 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 Organic Chemistry practice with other Chemistry topics or even switch to a totally different CXC 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 Organic Chemistry questions aligned to the official CXC CSEC Chemistry syllabus?
Every question is written against the published CXC CSEC Chemistry specification, including the exact command words (state, describe, explain, calculate, evaluate, etc.), mark allocations, and difficulty tier you'd see on a real CXC 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 CXC.
How is Organic Chemistry typically tested on CXC CSEC Chemistry papers?
Organic Chemistry appears across multiple question types on real CXC CSEC 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.
