How to Find Official Chemsheets A2 1079 Answers

Chemsheets is a copyrighted resource created by a UK-based educator. The official answers are not freely distributed on the public internet. Instead, they are provided to teachers and tutors who purchase the materials. As a student, your best sources for legitimate answers are:

  • Your class teacher – Ask for the answer booklet or a mark scheme after completing the sheet.
  • The official Chemsheets website – Schools with a site license can download answer packs.
  • Study groups – Collaborate with peers to compare answers before looking at the mark scheme.

Beware of unofficial "answer sharing" sites. Many contain errors, outdated specifications, or incomplete solutions that can harm your revision.

Scenario B: Haemoglobin and Ligand Exchange

Question: Explain why carbon monoxide is poisonous, using the concept of ligand exchange.

The Answer Logic:

  1. Haemoglobin (Hb) contains an $Fe^2+$ ion which coordinates with oxygen ($O_2$) reversibly.
  2. Carbon monoxide (CO) forms a stronger dative covalent bond with the $Fe^2+$.
  3. This is a ligand exchange reaction where $O_2$ is replaced by CO.
  4. The bond is so strong (high stability constant) that it is not readily reversible.
  5. This blocks the haemoglobin from carrying oxygen, leading to hypoxia.

Question Type 2: Multi-Step Synthesis

Typical prompt: Show how you would convert chlorobenzene into 4-nitrophenyl benzoate in three steps.

Expected answer logic:

  1. Step 1: Nitration of chlorobenzene (conc. HNO₃/H₂SO₄, 50°C) → 1-chloro-4-nitrobenzene.
    • Note: Chlorine is ortho/para directing, so major product is 4-nitro (p-nitro).
  2. Step 2: Hydrolysis of chloro group (NaOH(aq), high T and P, then acidify) → 4-nitrophenol.
  3. Step 3: Esterification with benzoyl chloride (C₆H₅COCl) in pyridine → 4-nitrophenyl benzoate.

Check your answers for: Correct reagents & conditions (temperature, solvent, catalyst), correct order of steps (don’t acylate before nitrating), and correct final structure.
