MCH-013 IGNOU Solved Assignment 2026-27

Academic Overview of MCH-013 Solved Assignment

The MCH-013: Coordination and Organometallic Chemistry Tutor Marked Assignment (TMA) is a compulsory continuous assessment component for students enrolled in the Master of Science in Chemistry (MSCCHEM) program under the School of Sciences (SOS). Accounting for 30% of the overall course weightage, this assignment evaluates advanced theoretical comprehension and analytical problem-solving skills in inorganic chemistry. The provided reference solutions are drafted strictly in accordance with IGNOU guidelines, respecting prescribed word counts for long, medium, and short-answer questions.

Syllabus Coverage and Core Topics

This reference solution package offers detailed answers across all prescribed curriculum blocks, ensuring deep technical clarity on complex chemical concepts:

• Crystal Field Theory and Ligand Field Theory: Complete calculations for Crystal Field Stabilization Energy (CFSE), d-orbital splitting patterns in octahedral, tetrahedral, and square planar geometries, Jahn-Teller distortion, and nephelauxetic series analysis.
• Organometallic Complexes: Structural, bonding, and electronic aspects of transition metal carbonyls, nitrosyls, metallocenes, and pi-complexes, adhering strictly to the 18-electron rule and electron-counting conventions.
• Kinetics and Reaction Mechanisms: Detailed steps for ligand substitution reactions in square planar and octahedral complexes, trans-effect theories, and electron transfer mechanism pathways (inner-sphere and outer-sphere).
• Homogeneous and Heterogeneous Catalysis: Industrial application mechanisms including Wilkinson's catalyst for hydrogenation, hydroformylation (oxo process), Monsanto acetic acid process, and Ziegler-Natta polymerization.
