ONR-3 IGNOU Handwritten Assignment 2026-27

ONR-3: Organic Chemistry Handwritten Assignment (Hard Copy)

This physical hard copy assignment is tailored for ONR-3: Organic Chemistry, a core course under IGNOU’s B.Sc. (Hons) Chemistry programme. The 80 GSM A4 ruled sheets are handwritten by experienced academic scribes, ensuring clarity, accuracy, and adherence to IGNOU’s prescribed format. The assignment includes the official IGNOU front page, printed question paper, and step-by-step solutions for all assigned questions.

Key Syllabus Units Covered

• Unit 1: Fundamentals of Organic Chemistry

  Covers classification of organic compounds, nomenclature (IUPAC), and basic concepts of bonding and hybridization in organic molecules. Includes handwritten explanations of sigma and pi bonds, resonance, and tautomerism with structural examples.

• Unit 2: Stereochemistry

  Detailed coverage of chirality, enantiomers, diastereomers, and optical activity. Solutions include Fischer projections, R/S nomenclature, and practical examples of chiral centers in biologically active molecules.

• Unit 3: Reaction Mechanisms

  Focuses on SN1/SN2 reactions, E1/E2 eliminations, and carbocation stability. Handwritten diagrams illustrate transition states, intermediates, and solvent effects with real-world examples like hydrolysis of alkyl halides.

• Unit 4: Aliphatic Compounds

  Explains classification, preparation, and reactions of alkanes, alkenes, alkynes, and their derivatives (haloalkanes, alcohols, ethers). Includes balanced chemical equations and mechanistic pathways for key reactions like Grignard reactions.

• Unit 5: Aromatic Compounds

  Covers benzene structure, electrophilic aromatic substitution (EAS), and directing effects of substituents. Handwritten solutions include mechanisms for nitration, sulfonation, and Friedel-Crafts reactions with structural representations.
