The boiling point of methane is −161.5°C while that of neon is −264°C.

Why is the boiling point of methane greater than that of neon?

AMolecules of methane have a larger surface area to form stronger intermolecular forces than those of neon

Correct. The tetrahedral CH₄ molecule has a larger surface area than a spherical Ne atom. Larger surface area increases polarisability and the strength of London dispersion forces, raising the boiling point.

BA molecule of methane has more electrons than an atom of neon.

Incorrect. CH₄has 6 (C) + 4×1 (H) = 10 electrons; Ne also has 10 electrons. They have the same electron count, so this cannot explain the difference in boiling point.

CA molecule of methane has a greater relative molecular mass than an atom of neon.

DMolecules of methane form hydrogen bonds, but those of neon do not.

Questions? Answers.

Is this for the new 9476 syllabus?▾

Yes. Every question, topic, and mark scheme is aligned to the 2026 syllabus.

I’m failing badly. Is it too late to start?▾

Students have gone from U at prelims to A at A-Levels. Shifu finds your weakest topics first so every hour counts.

How is this different from just doing TYS?▾

TYS gives you questions. Shifu tells you which questions to do, why you got them wrong, and what to fix next. It’s the difference between drilling blind and drilling smart.

Can I use it on my phone?▾

Yes. Works on any phone or tablet. Study on the MRT, at 2am, wherever.

I’m a private candidate. Will this work without a school?▾

Shifu is your school notes, tutor, and question bank in one app. No teacher required.

Is Shifu just another ChatGPT wrapper?▾

No. Shifu is built specifically for the H2 Chem syllabus, focusing on the content, keywords, and questions needed for A-Levels.
