Carbonyl compounds — Chemistry IAL Past Papers
47 papers, 2014–2025 · Unit 4, Unit 6, Unit 7
Every Chemistry IAL past paper in the collection that assesses carbonyl compounds.
By unit: all units (47) · Unit 4 (31) · Unit 6 (15) · Unit 7 (1)
Unit 4 : on 31 of 31 papers, 3–19 marks a paper (11 on average)Unit 6 : on 15 of 29 papers, 1–11 marks a paper (5 on average)Unit 7 : on 1 of 1 papers, 6 marks 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.
