How Alkyl Halides is examined
Alkyl Halides sits in the official PMDC Chemistry curriculum, the document that defines what can and cannot appear in the 2026 paper. Everything on this page is tagged against that curriculum rather than against a chapter list invented for a website, which is why a chapter here matches the chapter your textbook and your teacher use.
Chemistry carries 45 of the 180 questions in the real paper - 25% of your MDCAT score, and the MDCAT is half your merit aggregate. PMDC does not publish how those 45questions are split across chapters, so no honest page can tell you “expect four from Alkyl Halides”. What the archive can tell you is what actually appeared: 1 Alkyl Halides question out of the 48 Chemistry questions digitised so far.
That is a thin sample, and it is worth saying so plainly rather than dressing it up: with this few questions, the count tells you very little about how heavily Alkyl Halides is examined. It grows as the remaining papers are digitised.
Frequently asked questions
How many Alkyl Halides MCQs are on this page?
1, drawn from one past paper - the 2020 paper. Every one is transcribed from the real paper rather than written to look like a past paper question, and each carries the correct answer with a written explanation. 0 of them are readable in full without an account.
Is Alkyl Halides in the MDCAT 2026 syllabus?
Yes. Alkyl Halides is a chapter of the official PMDC Chemistry curriculum, and PMDC has confirmed the 2026 syllabus is unchanged from the 2025 revision, so everything on this page is still examinable.
How many Alkyl Halides questions come up in the MDCAT?
PMDC does not publish a per-chapter breakdown, so nobody can tell you a reliable number - be careful with pages that do. What can be counted is the paper as a whole: Chemistry is 45 of the 180 questions, and 2% of the Chemistry questions in our archive so far have come from Alkyl Halides.
Do these Alkyl Halides MCQs come with explanations?
Yes, and they are written from scratch rather than copied. An answer letter tells you nothing about why the other three options are wrong, which is the part that transfers to the next question. The first 0 questions of every paper are free to read in full; the rest need a pass.
This chapter has too few questions in the archive to be a useful search result yet, so it is not submitted for indexing. It becomes a full page as the remaining papers are digitised.
