Ethene is used to artificially ripen bananas exported from St. Lucia. What is the structural feature that makes ethene more reactive than ethane?

Q: How do I try a free CXC Integrated Science 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 CXC CSEC Integrated Science 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 CXC Integrated Science 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 Integrated Science questions aligned to the CXC CSEC syllabus?

Every question is written against the published CXC CSEC Integrated Science 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 CXC past papers. Explanations are written in the style of official examiner mark schemes so students learn exactly what marks are being awarded for.

Question

Ethene is used to artificially ripen bananas exported from St. Lucia. What is the structural feature that makes ethene more reactive than ethane?

Accepted Answer

Carbon-carbon double bond — Award 1 mark for identifying the C=C double bond. The double bond in alkenes makes them unsaturated and more reactive than saturated alkanes. A is incorrect — ethene has fewer carbons than ethane would suggest. C is incorrect — ethene has fewer H atoms. D is incorrect — ethene has no -OH group.

Answer

Carbon-carbon double bond

Answer

Longer carbon chain

Answer

Greater number of hydrogen atoms

Answer

Presence of a hydroxyl group
