Alkanes — Chemistry IAL Past Papers

34 papers, 2014–2025 · Unit 1, Unit 3

Every Chemistry IAL past paper in the collection that assesses alkanes.

By unit: all units (34) · Unit 1 (33) · Unit 3 (1)

• Unit 1: on 33 of 33 papers, 1–20 marks a paper (10 on average)
• Unit 3: on 1 of 32 papers, 1 mark a paper

Read question by question: blind checks found 112 of 120 question parts tagged with the right topic (95% confidence interval 87.4–96.6%). “needs (a)” names an earlier part the listed parts build on, and “then (c)” a later part that continues from them, so a question can be worked through whole.
