CHE-107 YCMOU Guess Paper, Solved PYQs, Notes 2026-27

Unlock 90% TEE Coverage for CHE-107 with YCMOU’s Most Accurate Guess Paper & Solved PYQs

YCMOU’s Continuous Assessment (CA) and Term-End Exam (TEE) demand precision—especially in Physical & Organic Chemistry, where conceptual clarity translates directly to marks. This Solved PYQs & Guess Paper bundle eliminates guesswork by providing 100% verified answers to past exam questions, including 2023-24 and 2024-25 TEE papers, meticulously mapped to YCMOU’s Self-Instructional Material (SIM) syllabus. For B.Sc. (Chemistry) students, this resource is the only study aid that bridges the gap between theoretical learning and practical application—critical for securing 60%+ marks in TEE.

Course Overview & Academic Objective

CHE-107 Physical & Organic Chemistry – I is a core 2nd-semester subject for YCMOU’s B.Sc. (Botany/Chemistry/Zoology) program, designed to develop foundational skills in:

• Theoretical understanding of chemical bonding, thermodynamics, and kinetics (SIM Unit 1-3)
• Problem-solving in organic reactions (SIM Unit 4-6), including mechanism-based questions
• Experimental correlation between theory and lab techniques (CA Home Assignments)

Key Syllabus Modules & Problem-Solving Methodology

This bundle covers all 6 core chapters of CHE-107’s 2023 Pattern syllabus, with a focus on high-weightage topics that repeatedly appear in TEE:

• Chapter 1: Chemical Bonding & Molecular Structure
  • Value-added feature: Includes VSEPR theory diagrams with solved numericals for sp³ hybridization problems—directly referenced in 2024 TEE Q10.
  • Exam strategy: Highlights 3-step problem-solving templates for bond angle calculations, used in 70% of CA Home Assignments.
• Chapter 4: Organic Reaction Mechanisms
  • Unique benefit: Provides step-by-step arrow-pushing explanations for SN1/SN2 reactions, with 2023 TEE Q12 model answer annotated for clarity.
  • YCMOU-specific: Aligns with Study Centre lab manual experiments (e.g., Grignard reaction), ensuring CA mark correlation.

Continuous Assessment & Exam Utility

Beyond TEE preparation, this resource is mandatory for:

• CA Home Assignments (गृहपाठ)
  • Pre-solved numericals for Unit 2 (Thermodynamics) with YCMOU’s exact question phrasing from 2025 CA Q3.
  • Lab technique correlations for Unit 5 (Spectroscopy), linking theory to Study Centre practical reports.
• Term-End Exam (TEE) Strategy
  • Guess Paper analysis: Identifies 8 recurring question patterns (e.g.,
