- Core questions: 46 questions worth 72 marks, split as 20 questions of 1 mark and 26 questions of 2 marks. This is the Chemistry core only, across Physical, Inorganic and Organic Chemistry, without General Aptitude.
- Time budget: The full paper allows 180 minutes for 65 questions, which is about 2.77 minutes per question, so the chemistry core earns roughly 128 minutes.
- Marking scheme: Negative marking applies only to MCQs, at one third of the marks allotted. A wrong 1 mark MCQ costs 0.33 and a wrong 2 mark MCQ costs 0.67. MSQ and NAT questions carry no negative marking.
- Paper format: 65 questions worth 100 marks in 180 minutes. General Aptitude is 15 marks and the Chemistry subject is the other 85, of which these sample papers drill a 72 mark core across the three pillars.
- Mode: Computer based test, with an on-screen calculator. Your own calculator is not allowed.
- Conducting body: The IITs and IISc by rotation. Chemistry (CY) is one of 30 GATE papers.
- Syllabus base: Physical Chemistry, Inorganic Chemistry and Organic Chemistry. Being a science paper, GATE Chemistry has no separate Engineering Mathematics section, and these papers leave out General Aptitude.
GATE Chemistry Exam Pattern and Marks Distribution 2027
The GATE Chemistry paper carries the same overall shape as every GATE paper, but the chemistry core is what these sample papers train you for. The structure below has held steady for years, so you can plan around it.
- Total paper: 65 questions worth 100 marks in 180 minutes, computer based, in English.
- Section split: General Aptitude 10 questions and 15 marks, and the Chemistry subject 55 questions and 85 marks, spread across Physical, Inorganic and Organic Chemistry.
- Core covered here: 46 questions and 72 marks, split as 20 questions of 1 mark and 26 questions of 2 marks. These sample papers deliberately leave out General Aptitude so you can focus on the chemistry core across the three pillars.
- Question types: MCQ with four options, MSQ where more than one option can be right, and NAT where you type a number.
- Marking: Only MCQs are penalised, at one third of the question's marks. MSQ and NAT carry no penalty at all, so an unsure NAT is always worth a guess.
- Conducting body: The IITs and IISc by rotation, announced each year on the official website gate2027.iitg.ac.in. Chemistry is one of 30 papers.
Note: The Chemistry core carries 72 marks and covers a wide range of topics, from Quantum Chemistry and Physical Chemistry to Coordination Chemistry, Organic Reaction Mechanisms, and Inorganic Chemistry. Focusing on only one area can leave gaps in your preparation. Solving a GATE Chemistry Sample Paper 2027 helps you revise Physical, Organic, and Inorganic Chemistry together in one sitting, making it easier to identify your strengths and the topics that need more attention before the exam.
GATE Chemistry Sample Papers - Why Recent Papers Matter Most
GATE does release its question papers, which puts you in a better position than most exams. But the Chemistry paper has drifted in emphasis, and older sets do not reflect where the marks now sit.
- NAT questions dominate the core: A large share of the 2 mark Chemistry questions are Numerical Answer Type, where you solve fully and type a value, such as a CFSE, a rate constant, a cell potential or a packing fraction. These carry no negative marking, so recent practice teaches you to attempt every one rather than skip.
- Mechanism and structure prediction weight has grown: Reaction mechanisms, stereochemistry and spectroscopy based structure elucidation now carry steady marks every year. Older papers under-represent them, so you can drill for weeks and still be light on mechanism reasoning.
- The three pillars stay fixed, the emphasis rotates: Physical, Inorganic and Organic Chemistry are always present, but the split between them shifts year to year. Solving a spread of recent GATE Chemistry sample papers is the only way to feel that balance.
GATE Chemistry Chapter Wise Weightage - High Scoring Topics to Focus in Sample Papers
The official CY syllabus groups the subject into three pillars, Physical, Inorganic and Organic Chemistry, each split into a few large areas. The 46 core questions spread across them with the physical and organic blocks carrying the most. The table below shows how our sample papers distribute them.
| Branch | Questions | Difficulty | What to Watch For |
|---|---|---|---|
| Physical Chemistry: Quantum and Spectroscopy | 6 | Moderate to Hard | Particle in a box, harmonic oscillator, the hydrogen atom, operators and eigenvalues, plus rotational, vibrational, electronic, NMR and ESR spectroscopy. Selection rules and energy level spacing show up as NAT most years. |
| Physical Chemistry: Thermodynamics, Kinetics and Electrochemistry | 8 | Moderate to Hard | Laws of thermodynamics, partition functions, phase and chemical equilibria, rate laws and mechanisms, Arrhenius behaviour, the Nernst equation and conductance. The largest single block and a heavy NAT source. |
| Inorganic Chemistry: Main Group and Periodic Properties | 6 | Moderate | Periodic trends, structure and bonding of the s and p block, boranes, silicates, HSAB acids and bases and noble gas compounds. Direct and quick once the trends are memorised. |
| Inorganic Chemistry: Coordination Compounds and Organometallics | 6 | Moderate to Hard | Crystal field theory, CFSE, magnetism, isomerism, the spectrochemical series, the 18 electron rule, metal carbonyls and common organometallic reactions. Magnetic moment and CFSE are frequent NAT items. |
| Inorganic Chemistry: Solid State and Bioinorganic | 3 | Moderate | Close packing, unit cells, radius ratio, band theory and defects, plus metalloenzymes and oxygen carriers. Small weight, but unit cell and packing fraction numericals are quick marks. |
| Organic Chemistry: Stereochemistry and Reaction Mechanisms | 7 | Moderate to Hard | R and S, E and Z, conformations, chirality and optical activity, plus SN1, SN2, E1, E2, addition and rearrangement mechanisms. Stereochemical outcome questions catch people who rush. |
| Organic Chemistry: Named Reactions and Synthesis | 7 | Moderate | Aldol, Grignard, Wittig, Diels-Alder, Cannizzaro, Hofmann and Claisen among other named reactions, plus multistep synthesis and functional group interconversion. Reagent and product prediction dominates. |
| Organic Chemistry: Pericyclic, Photochemistry and Biomolecules | 3 | Moderate to Hard | Electrocyclic, cycloaddition and sigmatropic reactions, the Woodward-Hoffmann rules, basic photochemistry, and carbohydrates, amino acids and nucleic acids. Small but rule heavy, so easy to lose if you skip it. |
Note: Do not let the two 3 question blocks slide just because they are small. Solid State and Bioinorganic together with Pericyclic, Photochemistry and Biomolecules are 6 questions and often more than 10 marks, the numericals and rule based questions are short, and they need far less preparation time per mark than a full mechanism problem. In a GATE Chemistry sample paper these are the areas where careful candidates finish fast and bank certain marks.

How to Use GATE Chemistry Sample Papers to Clear in First Attempt
The chemistry core rewards two things, breadth and clean working. Your preparation should push you across Physical, Inorganic and Organic Chemistry while cutting the small slips that cost you sure marks.
- Time every paper at 128 minutes. That is the pace the chemistry core earns inside the full 180. If you routinely take 160, you are borrowing the time General Aptitude will need on exam day.
- Attempt every NAT. A large part of the 2 mark load is Numerical Answer Type with no negative marking, so a solved value or even a careful estimate is always better than a blank.
- Log why you got it wrong, not just what. Wrong sign in a thermodynamic step, missed unit conversion, or genuinely did not know the mechanism. Those three need three different fixes.
- Balance your revision by pillar. A steady 60 percent can hide the fact that every miss is Physical or Organic. Track score per pillar, not just the total.
- Do not skip the 1 mark questions. Twenty of them carry 20 marks between them and take the least time per mark in the paper.
- Rework each paper's organic section. Stereochemistry, mechanisms and named reactions carry a heavy share and reward a second pass more than rote physical formulas do.
GATE Chemistry Negative Marking and Attempt Strategy
GATE's marking scheme is more forgiving than most students assume, but only if you know which question type you are looking at. Getting this wrong costs marks that nothing else will win back.
- Only MCQs are penalised. The deduction is one third of the marks allotted, so a wrong 1 mark MCQ costs 0.33 and a wrong 2 mark MCQ costs 0.67.
- Never leave a NAT blank. Numerical Answer Type questions carry no negative marking, and they make up a big share of the Chemistry core, from CFSE and rate constants to cell potentials. An unsure value is free, and a blank is a guaranteed zero.
- MSQ needs all or nothing. Multiple Select Questions carry no penalty either, but partial ticks earn nothing. Only mark the options you are sure of, and remember there may be just one.
- On MCQs, eliminate before you guess. A blind guess across four options is a losing trade at one third negative. Once two options are gone, on a 2 mark coordination or mechanism MCQ, it turns clearly in your favour.

FAQs on GATE Chemistry Sample Papers 2027
Ques.How many questions and marks does the GATE Chemistry core carry in these sample papers?
Ans.Each GATE Chemistry sample paper carries 46 questions worth 72 marks, made up of 20 questions of 1 mark and 26 questions of 2 marks. This is the chemistry core across Physical, Inorganic and Organic Chemistry, so it leaves out General Aptitude, which is a separate common section. In the real exam the full paper is 65 questions and 100 marks, with General Aptitude taking 15 marks.
Ques.Is there negative marking in the GATE Chemistry paper?
Ans.Only on MCQs, and the deduction is one third of the marks allotted to that question. So a wrong 1 mark MCQ costs you 0.33 and a wrong 2 mark MCQ costs 0.67. Multiple Select Questions and Numerical Answer Type questions carry no negative marking at all, which matters a lot in Chemistry because so much of the core is NAT. Never leave a NAT question blank.
Ques.How much time should I spend on the Chemistry core in the real exam?
Ans.Budget about 128 minutes for the 46 core questions. The paper gives 180 minutes for 65 questions, which is roughly 2.77 minutes per question, so 46 chemistry core questions earn about 128 minutes. That leaves the remaining time for General Aptitude. Practising a full GATE Chemistry sample paper at this pace is the best way to keep that balance under real pressure.
Ques.Which pillars carry the most weight in the GATE Chemistry paper?
Ans.Physical Chemistry and Organic Chemistry usually carry the most, covering quantum and spectroscopy, thermodynamics, kinetics and electrochemistry on the physical side, and stereochemistry, reaction mechanisms and named reactions on the organic side. Inorganic Chemistry, spanning main group, coordination, organometallics and solid state, comes close behind. Our sample papers spread the 46 questions across all three pillars so you are never blindsided by an area you skipped.
Ques.Do these sample papers include General Aptitude and Engineering Mathematics?
Ans.No. These GATE Chemistry sample papers cover only the chemistry technical core of 46 questions and 72 marks. General Aptitude is a common part of the full paper and is provided separately, and being a science paper GATE Chemistry has no separate Engineering Mathematics section, so you can drill the Physical, Inorganic and Organic core on its own without diluting your practice.
Ques.Are these GATE Chemistry sample papers the same as previous year papers?
Ans.No. GATE does publish its past papers, and you should solve those too. These are original questions written to the current pattern, with 46 core questions in 128 minutes and the 20 plus 26 mark split, so you get fresh practice once you have exhausted the official sets. They also weight NAT questions, mechanisms and spectroscopy the way recent Chemistry papers do, which older past papers under-represent.
