Q: How do I try a free WJEC Chemistry question?

Just tap any of the four options on this page — no signup, no card, nothing to install. You'll see the correct answer and a full mark-scheme-style explanation within a second. Each visit shows a fresh randomly-picked question from the live WJEC GCSE Chemistry bank, so you can keep refreshing to try different ones before deciding whether to create a free account for daily access.

Q: Is Kramizo really free for WJEC Chemistry students?

Yes — completely free. Every student gets 45 questions a day on the free plan, across any board and any subject, with no card required and no trial countdown. Kramizo's optional Pro plan removes the daily cap and adds analytics, but the free plan is genuinely free forever. We make money from the small percentage of students who choose to upgrade — not from selling data or ads.

Q: Are the Chemistry questions aligned to the WJEC GCSE syllabus?

Every question is written against the published WJEC GCSE Chemistry syllabus and reviewed for accuracy before being added to the bank. We match the command words (state, describe, explain, evaluate), mark allocations, and difficulty tier you'll see on real WJEC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Which of the following pairs correctly matches an organic compound to its homologous series?

Accepted Answer

CH₂=CH₂ — alkene — CH₂=CH₂ is ethene, which contains a C=C double bond and belongs to the alkene series. CH₃CH₂OH is ethanol, an alcohol; CH₃COOH is ethanoic acid, a carboxylic acid; and CH₃CH₃ is ethane, an alkane — not an alkyne.

Answer

CH₂=CH₂ — alkene

Answer

CH₃CH₃ — alkyne

Answer

CH₃CH₂OH — carboxylic acid

Answer

CH₃COOH — alcohol
