IMAT Chemistry Sample Questions
Questıon 1 · Stoıchıometry
Step 1: H₂SO₄ contains 4 oxygen atoms per formula unit.
Step 2: 1 mole H₂SO₄ → 4 moles O atoms
Step 3: 0.5 mol H₂SO₄ → 0.5 × 4 = 2 mol O atoms
Answer: C) 2.0
Questıon 2 · Gas Laws
Graham’s law: Diffusion rate ∝ 1/√(molar mass)
Molar masses: O₂=32, N₂=28, CO₂=44, He=4, CH₄=16
Lowest molar mass → highest rate: He (4 g/mol)
Answer: D) He
Questıon 3 · Organıc Chemıstry
Alcohols: contain −OH (hydroxyl).
Carboxylic acids: contain −COOH (carboxyl) which includes a carbonyl (C=O) + hydroxyl (−OH).
Common group: Hydroxyl (−OH)
Answer: B) Hydroxyl
5 Most Common Mistakes in IMAT Chemistry
- Unit confusion: Moles, grams, liters, atm – always verify units, especially in gas law problems.
- Incorrect oxidation numbers: Redox questions demand precise oxidation state determination.
- Memorizing gas law formulas without understanding: Knowing PV=nRT is not enough; understanding what remains constant is crucial.
- Mixing up functional groups: Aldehyde vs ketone, carboxylic acid vs ester cause frequent errors.
- Calculator dependency: IMAT does not allow calculators. Numbers are clean, but mental math practice is essential.

Everything you need to know about IMAT Chemistry
How many chemistry questions are on the IMAT?
Typically 15 chemistry questions out of 60 total in the Scientific Knowledge section (Biology ~23, Physics & Math ~13, Logic ~7).
What is the difficulty level of IMAT Chemistry?
Similar to IGCSE Core–Extended and AS-Level fundamentals. Comparable to 9th–10th grade chemistry in Turkey, but English terminology is crucial.
Is organic chemistry heavily tested?
No mechanisms — only recognition, classification, and basic properties of functional groups. Master the names and groups and you're set.
Can I use a calculator during the exam?
No. All questions are designed to be solved with simple, clean numbers. Speed and accurate setup matter most.
Which resources should I use?
Cambridge IGCSE Chemistry textbooks, past IMAT papers, and tailored tutoring notes. Our courses combine all three for a focused plan.
