CHE-1 IGNOU Guess Paper 2026-27

PAPER-2026 (Course Code PAPER-2026) Guess Paper 2026-27 (Digital PDF)

The following structured guess paper aligns with the IGNOU Academic Coursework for PAPER-2026 (English/Hindi) and covers key scoring topics from the Term-End Exam (TEE) pattern. It includes chapter-wise question weightage, solved previous year questions (June & Dec sessions), and time-management strategies for the 3-hour exam.

Key Syllabus Blocks & Focus Areas

1. Unit 1: Fundamental Concepts of Chemistry

• Focus on atomic structure, chemical bonding, and periodic trends—highly recurring in TEE.
• Prioritize numerical problems on Avogadro’s number and molarity.
• Expect 2–3 questions on VSEPR theory and hybridization.

2. Unit 2: Thermodynamics and Chemical Kinetics

• Master Laws of Thermodynamics (1st, 2nd, 3rd) with problem-solving on ΔG, ΔH, ΔS.
• Dedicate time to rate laws, activation energy, and catalysis—common in numericals.
• Practice Gibbs free energy calculations for equilibrium questions.

3. Unit 3: Quantum Chemistry and Spectroscopy

• Emphasize Schrödinger equation, quantum numbers, and atomic orbitals.
• Prepare for UV-Vis, IR, NMR spectroscopy interpretation questions.
• Expect 1–2 descriptive questions on molecular orbital theory.

4. Unit 4: Chemical Bonding and Molecular Geometry

• Revise Lewis structures, resonance, and bond polarity.
• Focus on VSEPR and valence bond theory for geometry-based questions.
• Practice bond dissociation energy and bond order calculations.

5. Unit 5: Practical Chemistry (Lab Focus)

• Expect 1–2 questions on experimental techniques (e.g., titration, chromatography).
• Review error analysis and precision vs. accuracy concepts.
• Prepare short-answer questions on qualitative analysis (e.g., cation/anion tests).

Exam Time Management Tips

• Allocate 45 minutes for numerical problems (Units 1–3) and 30 minutes for theory (Units 4–5).
• Attempt short-answer questions first (10–12 marks), then proceed to long-answer questions.
• For spectroscopy questions (Unit 3), prioritize interpretation over memorization.

Subject-Specific FAQs

Q: How many numerical questions are typically asked in PAPER-2026? A: Around 6–8 numerical questions (1–2 per unit) are common, carrying 20–25 marks in total.

Q: Are descriptive questions from Unit 5 (Practical Chemistry) weight-heavy? A: Yes, 15–20 marks are often allocated to lab-based questions, including error analysis and technique explanations.
