CHE-121 YCMOU Assignment Answers 2026-27

Earn 30% of your CHE-121 marks effortlessly with this YCMOU-verified Home Assignment (गृहपाठ) solution set for the 2026-27 academic year. Designed exclusively for M.Sc. (Chemistry) {2022 Pattern} students, this resource eliminates guesswork by providing step-by-step derivations for all 12 assigned questions—directly mapped to the Inorganic Chemistry-II syllabus and Continuous Assessment criteria. No generic answers: every solution adheres to YCMOU’s Self-Instructional Material (SIM) guidelines, ensuring your responses align with Term-End Exam (TEE) expectations.

Course Overview & Academic Objectives

CHE-121 Inorganic Chemistry-II builds on foundational concepts introduced in CHE-101, focusing on transition metal complexes, coordination chemistry, and advanced spectroscopic techniques. YCMOU’s curriculum emphasizes theoretical rigor and applied problem-solving, with a 30% weightage allocated to Home Assignments (गृहपाठ) in Continuous Assessment. This resource bridges the gap between theoretical learning and practical application, ensuring students can:

• Derive equilibrium constants for coordination compounds using Jahn-Teller distortion principles (Syllabus Unit 3).
• Apply VBT and MO Theory to predict magnetic properties of octahedral complexes (Syllabus Unit 4).
• Solve spectral data problems using IR, UV-Vis, and NMR spectroscopy (Syllabus Unit 5).
• Cite IUPAC nomenclature rules for organometallic compounds (Syllabus Unit 2).

Key Syllabus Modules & Chapter-Specific Solutions

Each Home Assignment (गृहपाठ) in this set corresponds to a specific chapter from the YCMOU Self-Instructional Material (SIM) for CHE-121. Solutions include:

• Chapter 1: Advanced Coordination Chemistry (10 marks)
  • Problem 1.2: Calculate the crystal field splitting energy (Δ_o) for [Co(NH₃)₆]³⁺ using spectrochemical series data, with explicit reference to ligand field strength (YCMOU TEE 2025 Q2).
  • Problem 1.5: Explain the VBT hybridization in [Ni(CN)₄]^2-, including geometric isomerism considerations (SIM pg. 42).
• Chapter 3: Bioinorganic Chemistry (8 marks)
  • Problem 3.4: Compare the oxygen-binding mechanisms of hemoglobin and myoglobin, using Le Chatelier’s principle to explain Bohr effect (YCMOU CA guidelines).
  • Problem 3.7: Derive the E_1/2 values for [Fe(CN)₆]^3-/4- redox couple, citing Nernst equation with n=1 (SIM pg. 78).
• Chapter 5: Organometallic Chemistry (12 marks)
  • Problem 5.3: Name [RhCl(PPh₃)₂(CO)] using IUPAC rules, including ligand priority order (YCMOU TEE 2024 Q5).
  • Problem 5.8: Predict the 13C NMR shifts for ferrocene, referencing hapticity and π-backbonding (SIM pg. 110).

Continuous Assessment & Exam Utility

This resource is directly aligned with YCMOU’s CA marking scheme:

• Home Assignments (गृहपाठ): Solutions include detailed step-by-step reasoning for all 12 questions, ensuring full marks in the 30% CA component. Each answer is formatted to match YCMOU’s answer sheet guidelines, with clear labeling of sub-questions and boxed final answers.
• Term-End Exam (TEE) Preparation: Problems mirror past TEE question patterns, including numerical, theoretical, and application-based questions. For example:
