CHE-010 IGNOU Solved Assignment 2026-27

CHE-010 Solved Assignment 2026–27: Chemistry (CHE-010) TMA Solutions

This verified digital PDF solution set for CHE-010 (Chemistry) addresses the Tutor-Marked Assignment (TMA) requirements for the 2026–27 academic session, covering 30% of course weightage with plagiarism-free, university-approved answers. Below are key syllabus blocks addressed in the assignment, along with structured solutions and FAQs.

1. Core Syllabus Units Addressed

• Unit 1: Fundamental Concepts of Chemistry
  • Atomic structure, molecular orbital theory, and periodic trends with emphasis on quantum numbers and electron configurations.
  • Detailed solutions for problems on bonding in diatomic molecules (e.g., O₂, N₂) using MO theory.
• Unit 2: Chemical Thermodynamics and Kinetics
  • First and second laws of thermodynamics applied to real-world processes (e.g., Gibbs free energy calculations for spontaneous reactions).
  • Rate laws, activation energy, and reaction mechanisms (e.g., S_N1 vs. S_N2 mechanisms in organic substrates).
• Unit 3: Stereochemistry and Organic Reaction Mechanisms
  • Chirality, R/S nomenclature, and conformational analysis (e.g., cyclohexane chair forms).
  • Step-by-step solutions for mechanistic pathways (e.g., electrophilic aromatic substitution in benzene derivatives).
• Unit 4: Coordination Chemistry and Molecular Analysis
  • Coordination compounds: Naming, isomerism (geometric/optical), and VBT/CFT explanations.
  • Spectroscopic techniques (UV-Vis, IR) for identifying coordination environments (e.g., [Co(NH₃)₆]³⁺ vs. [Co(CN)₆]³⁻).
• Unit 5: Practical Laboratory Applications
  • Experimental procedures for titrations (acid-base, redox) with error analysis.
  • Qualitative inorganic analysis workflows (e.g., cation/anion separation schemes).

2. Sample Problem Solutions

Each unit includes step-by-step solutions for typical TMA questions, such as:

• Thermodynamics: Calculate ΔG° for the reaction N₂(g) + 3H₂(g) 2NH₃(g) given ΔH° and ΔS° values (word limit: 250).
• Stereochemistry: Draw all stereoisomers of 2-bromo-3-chloropentane and assign R/S configurations (word limit: 100).
• Coordination Chemistry: Predict the magnetic properties of [Fe(CN)₆]⁴⁻ using crystal field theory (word limit: 500).

3. Subject-Specific FAQs

• Q: How do I balance word limits for TMA questions?

  Use concise chemical notation (e.g., ΔG° = ΔH° TΔS°) and prioritize key steps. For example, in thermodynamics problems, include units and sign conventions explicitly to save words.

• Q: Are diagrams allowed in TMA answers?

  Yes, but they must be hand-drawn and labeled clearly (e.g., resonance structures for benzene). Avoid digital images; use text descriptions where possible (e.g., ‘Draw the chair conformation of trans-1,2-dimethylcyclohexane’).

4. Submission Compliance Notes

• Adhere to IGNOU’s 2026–27 TMA submission deadlines (typically 31st July/31st January).
• Use only the approved question paper (available on IGNOU’s official portal) to avoid mismatches.
• Solutions are formatted in PDF with page numbers for easy referencing.
