The VCE Chemistry examination is divided into two distinct sections—Paper 1 (multiple choice) and Paper 2 (short answer)—each designed to assess a different set of skills aligned with the VCE Chemistry Study Design. Recognising the structure and expectations of each paper is critical for students preparing for their final assessment. Below is a breakdown of the two papers and their key differences.
Easiest and Hardest Questions
According to the 2024 examiner report:
- Easiest Question:
- Question 7 (Paper 1) – This question tested students' understanding of stoichiometry and Faraday’s laws in electroplating. An impressive 63% of students correctly calculated the mass of copper deposited from a known quantity of electrons, indicating a strong grasp of this commonly practised concept.
- Hardest Question:
- uestion 1a (Paper 2) – This question asked students to explain how melting point determination is used to assess the purity and identity of a compound. A striking 43% of students scored zero, and only 11% achieved full marks, largely due to confusion between melting point value and melting point range as indicators of purity.

How Paper 1 Assesses the Chemistry Syllabus
To help students and teachers prepare more strategically, it’s important to know exactly which parts of the syllabus each Paper 1 question targets, and how students performed on each. Below, you’ll find a detailed mapping of every multiple-choice question from the 2024 VCE Chemistry exam to its general and specific syllabus topic. This is paired with the percentage of students who answered each question correctly, revealing patterns of strength and challenge areas.
Note: Some questions (e.g., 10 and 27) were excluded due to all options being accepted as correct, as per VCAA assessment review.
Key Takeaways
This mapping highlights that while students performed strongly on core calculations (e.g., electroplating, use of calibration curves, and protein structure), there were notable challenges in areas such as catalysis, alkaline half-equations, and complex organic structure identification. Electrochemistry remains an area of both strength and difficulty, while advanced equilibrium and analytical techniques also present hurdles for many.

Common Mistakes in 2024
- Incorrect or Incomplete Calculations: Many students lost marks on questions requiring step-by-step stoichiometry or energy calculations due to missed steps or arithmetic errors.
- Misinterpreting Melting Point Data: A widespread misconception was assuming that a lower melting point always means impurity, without considering the melting point range as a crucial indicator.
- Poor Use of Units: Students frequently omitted units for calculated values when the unit was not provided in the question, particularly for mass or energy.
- Weakness with Half-Equations in Alkaline Media: Balancing equations in basic (alkaline) conditions was poorly handled by a majority of students, highlighting the need for more targeted practice.
- Overlooking Details in Multiple-Choice Distractors: Several questions saw students tricked by plausible but incorrect distractors, especially in topics like equilibrium and organic structure.
- Not Using the Data Book Correctly: Misreading or underusing data from the Data Book, especially for bond enthalpies and standard reduction potentials, led to errors in several questions.
How Paper 2 Assesses the Chemistry Syllabus
Paper 2 of the VCE Chemistry exam is designed to test students’ ability to apply their knowledge through structured, multi-part questions. Each sub-question targets a specific aspect of the syllabus, assessing both breadth and depth of understanding.
The table below maps each sub-question from the 2024 exam to its corresponding general and specific topic, and shows how students performed at each mark level, highlighting areas of strength and challenge.
