What These Chemistry Papers Cover Inside
The two papers test the core Class 10 Chemistry syllabus. The 2017 paper asks you to fill blanks on hydrocarbon reactions and periodic table trends. It also requires balanced chemical equations for reactions like silver nitrate with hydrochloric acid.
The 2026 paper includes 15 multiple-choice questions. These cover electrolysis, metallurgy, industrial preparation of nitric acid, and IUPAC nomenclature. It also features assertion-reason questions that test conceptual depth.
Exam Pattern: 2017 vs 2026 Papers
The two papers share an 80-mark structure split into two sections, but their durations and section formats differ. You must check each paper’s instructions before practising.
| Paper | Year | Maximum Marks | Time Allowed | Section A Format |
|---|---|---|---|---|
| Half-Yearly | 2017 | 80 | 2 Hrs. 15 min | Fill-in-the-blanks, equations, observations |
| Second Term | 2026 | 80 | 2 Hrs. | 15 multiple-choice questions |
Both papers allocate 40 marks to Section A and require you to attempt all questions. The 2017 paper uses descriptive sub-questions worth 5 marks each. The 2026 paper starts with an MCQ block worth 15 marks.
Topics That Recur Across Both Papers
Certain topics appear in both the 2017 and 2026 papers, making them high-priority for your study plan. The grounding excerpts show clear overlaps in the question themes.
- Periodic table trends: The 2017 paper tests metallic and non-metallic character across periods and groups.
- Chemical bonding and electrolysis: The 2026 paper asks how electricity is conducted in molten electrolytes and acid solutions.
- Study of acids, bases, and salts: The 2017 paper asks for observations when sodium hydroxide reacts with ferrous chloride. The 2026 paper covers cupric chloride reactions with ammonium hydroxide.
- Organic chemistry: The 2017 paper tests ethylene with bromine water. The 2026 paper asks for the IUPAC name of formic acid.
- Metallurgy: The 2026 paper includes a question on the main components of brass.
Worked Example: Balancing a Reaction Equation
The 2017 paper asks for a balanced equation when silver nitrate reacts with dilute hydrochloric acid. This is a double displacement reaction. The products are a white precipitate and a soluble acid.
AgNO_3(aq) + HCl(aq) \rightarrow AgCl(s) \downarrow + HNO_3(aq)
Silver chloride (AgCl) forms as a white precipitate. Check that the number of atoms for each element matches on both sides. You should have one silver, one nitrogen, three oxygen, one hydrogen, and one chlorine atom on each side.
How to Use These Papers for Preparation
Solving past papers is only useful if you simulate exam conditions and review your mistakes. Follow these steps to get the most out of these downloads.
- Check the time limit: Set a timer for the exact duration printed on the paper you are solving. Use 2 hours and 15 minutes for the 2017 paper. Use 2 hours for the 2026 paper.
- Attempt Section A first: Both papers require you to attempt all Section A questions. Answer every part, even if you are unsure, because there is no negative marking.
- Write balanced equations fully: Include state symbols like (aq), (s), and (g) where applicable. Examiners look for the correct precipitate arrow (\downarrow) or gas arrow (\uparrow).
- Review against the marking scheme: The 2017 paper uses 5-mark blocks. Ensure your answer for a 5-mark question includes five distinct points or a fully balanced equation with observations.

Common Mistakes Students Make With These Papers
Students lose marks on Chemistry papers by ignoring the specific instructions in the question. Avoid these common errors when practising.
- Ignoring the mark allocation: A 5-mark observation question requires five distinct observations. Writing one observation and explaining it in detail will not earn full marks.
- Unbalanced equations: The 2017 paper explicitly asks for balanced chemical equations. Always count the atoms on both sides before moving to the next question.
- Confusing addition and substitution: The 2017 paper tests whether you know that saturated hydrocarbons undergo substitution, while unsaturated hydrocarbons undergo addition. Mixing these up is a frequent error.
- Skipping IUPAC naming rules: The 2026 paper asks for the IUPAC name of formic acid. Remember that formic acid is methanoic acid, not ethanoic acid.
Frequently Asked Questions
How many Chemistry papers are available for download?
There are exactly two papers available. One is the 2017 half-yearly examination, and the other is the 2026 second-term examination.
Do both papers have the same time duration?
No, the durations differ. The 2017 paper allows 2 hours and 15 minutes. The 2026 paper allows 2 hours.
What is the maximum marks for each paper?
Both papers carry a maximum of 80 marks. Each paper divides the marks into two sections of 40 marks each.
Are these papers solved or do they include marking schemes?
The downloads provide the question papers. They do not include solved answers or official marking schemes. You should use your textbook to verify your answers.
