Carboxylic acid derivatives in Unit 4 — Chemistry IAL Past Papers

30 papers, 2014–2025 · Unit 4

The Chemistry IAL Unit 4 — Rates, Equilibria and Further Organic Chemistry past papers in the collection that assess carboxylic acid derivatives.

By unit: all units (37) · Unit 4 (30) · Unit 6 (7)

Unit 4: on 30 of 31 papers, 1–10 marks a paper (4 on average)

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.
