Course Overview & Academic Objective

CHE-141 (Stereochemistry) is a core module in the M.Sc. (Chemistry) program, focusing on spatial arrangements of atoms in molecules and their impact on chemical reactivity. YCMOU’s curriculum emphasizes:

• Conformational analysis of cycloalkanes and acyclic systems (Unit 2)
• Chirality and stereoisomerism (Unit 3), including R/S nomenclature and Fischer projections
• Mechanistic insights into stereospecific reactions (Unit 4), critical for Term-End Exam (TEE) problem-solving

Key Syllabus Modules & Chapter Breakdown

Each solution set mirrors YCMOU’s Self-Instructional Material (SIM) structure, with solutions organized by:

• Chapter 1: Basics of Stereochemistry
  • Detailed derivations for meso compounds and enantiomeric excess calculations (with practical examples from YCMOU’s past assignments)
  • Step-by-step resolution of optical rotation problems using specific rotatory power data
• Chapter 3: Stereospecific Reactions
  • Mechanistic pathways for SN1/SN2 reactions with stereochemical outcomes (e.g., inversion vs. retention), annotated with YCMOU’s preferred notation
  • Problem sets on pericyclic reactions (Diels-Alder, sigmatropic shifts) with conformational energy diagrams for visual learners
• Chapter 5: Practical Applications
  • Case studies on asymmetric synthesis using chiral auxiliaries, referenced to YCMOU’s Study Centre (अभ्यास केंद्र) lab manuals
  • Solutions for PRN-based problem sets (e.g.,
