CHE-009 IGNOU Solved Assignment 2026-27

CHE-009 Solved Assignment 2026–27: Chemistry (CHE-009) Verified TMA Solutions

The following content mirrors the mandatory 30% course weightage for the Tutor Marked Assignment (TMA) of IGNOU’s CHE-009 Chemistry, aligned with the 2026–27 academic session. Solutions are structured per official IGNOU curriculum units and include step-by-step derivations, numericals, and analytical explanations for reaction kinetics, stereochemistry, and coordination chemistry.

Key Syllabus Units Covered in TMA Solutions

• Block 1: Fundamental Principles of Chemistry
  • Atomic structure and quantum mechanics (wave functions, orbitals, and spectral series).
  • Bonding theories (VSEPR, hybridization, and molecular orbital theory) with solutions for hybridization problems.
  • Thermodynamics: First Law (ΔU = q + w), Gibbs free energy (ΔG = ΔH TΔS), and entropy calculations.
• Block 2: Chemical Kinetics and Reaction Mechanisms
  • Rate laws, order of reactions, and determination of rate constants (k) via integrated rate equations.
  • Mechanisms: SN1 vs. SN2, E1 vs. E2 reactions with mechanistic pathway diagrams.
  • Catalysis (homogeneous/heterogeneous) and transition-state theory.
• Block 3: Organic Chemistry: Stereochemistry and Reaction Mechanisms
  • Stereoisomerism (R/S, E/Z configurations) with Fischer projections and conformational analysis.
  • Mechanisms of electrophilic/ nucleophilic aromatic substitution and pericyclic reactions.
  • Solutions for retrosynthetic analysis of complex organic molecules.
• Block 4: Coordination Chemistry and Solid-State Chemistry
  • Valence Bond Theory (VBT) vs. Crystal Field Theory (CFT) for transition metal complexes.
  • Isomerism (structural, linkage, optical) with IUPAC naming conventions.
  • Magnetic properties and spectral data interpretation (UV-Vis, IR).
• Block 5: Analytical Techniques and Laboratory Science
  • Spectroscopic methods (NMR, IR, UV-Vis) with spectral peak assignments.
  • Titration calculations (acid-base, redox) and standardization of solutions.
  • Chromatographic techniques (TLC, GC) and R_f value calculations.

FAQs for CHE-009 TMA Solutions

• Q: Are the solutions strictly within the 500-word limit for Q1?

  A: Yes. Each solution adheres to the word-count constraints specified in the IGNOU assignment guidelines, with concise yet comprehensive explanations for numericals and theoretical questions.

• Q: How are lab-based questions (e.g., spectroscopy) addressed?

  The solutions include step-by-step derivations for spectral data interpretation (e.g., NMR splitting patterns) and calculated R_f values with clear lab-based reasoning.
