Study Notes
Learning Outcomes
- Students will understand the history and importance of organic chemistry.
- Ability to describe how carbon's structure affects bond formation.
- Knowledge of functional groups for naming organic compounds.
- Proficiency in IUPAC nomenclature and structural formulas of organic compounds.
- Skills to reflect on organic compounds used as home remedies for immune support against Covid-19.
Introduction to Organic Chemistry
- Organic chemistry studies carbon-containing compounds, focusing on their composition, structure, properties, and preparation.
- Approximately 98% of known compounds are organic.
- Organic compounds are divided into natural (e.g., carbohydrates, fats, proteins) and synthetic (e.g., rubbers, plastics, pesticides).
History and Relevance of Organic Chemistry
- Coined by Jöns Jacob Berzelius in 1807, who believed organic compounds arose exclusively from living organisms (Vital Force Theory).
- Friedrich Wöhler synthesized urea from ammonium cyanate in 1828, disproving the Vital Force Theory.
- Wöhler's work introduced isomerism, showing compounds can have the same formula but different structures.
Key Figures
- Friedrich August Kekulé established foundational ideas of chemical bonding:
- Carbon has a valence of four.
- Carbon can form chains of any length and complexity.
- Reaction products provide insights into chemical structure.
Importance of Organic Compounds
- Organic compounds play vital roles in everyday life, influencing food, health, agriculture, textiles, and household products.
- Key organic products include:
- Food: Flour, sugar, bread, meat, dairy.
- Health: Medicines like penicillin, ibuprofen, morphine.
- Textiles: Cotton, silk, nylon, wool.
- Agriculture: Pesticides, insecticides, fertilizers (urea).
- Household: Bath soaps, vinegar, soy sauce, plastics, paints.
Conclusion
- Understanding organic compounds enhances quality of life through diverse applications in various sectors.
