Study Notes
History of Organic Chemistry
- Alchemy, dominant before the 1600s, led to the production of pure compounds and various laboratory tools.
- Between the 1300s and 1500s, fractionation techniques for producing alcoholic beverages like whisky and brandy were developed.
- Isolation of organic compounds began, exemplified by acetic acid from vinegar and formic acid from ants.
Birth of Modern Chemistry
- In the 1600s to 1700s, Torbern Bergman distinguished organic from inorganic compounds, linking organic substances to the animal and vegetable realms.
- Hilaire Rouelle isolated urea from human urine, marking progress in organic chemistry.
- Antoine Lavoisier classified organic compounds consisting of carbon (C), hydrogen (H), nitrogen (N), and phosphorus (P), establishing a foundational framework.
- Jons Jakob Berzelius introduced the vitalism theory, proposing that organic compounds originated from a vital force in living organisms.
Developments in the 1800s
- Michel Chevreul created soap from animal fat and alkali, isolating fatty acids in the process.
- Friedrich Wöhler synthesized urea from ammonium cyanate, a landmark act considered the birth of organic chemistry.
- Edward Frankland advanced the concept of valence, shaping modern understandings of chemical bonding.
- Notable chemists like Stanislao Cannizzaro, A. Kekulé, and Emil Erlenmeyer contributed to understanding molecular weights and bonding structures.
20th Century Concepts
- The modern view of chemical bonding emerged with ionic and covalent bonding models proposed by W. Kossel and G.N. Lewis.
- Quantum mechanics contributed to understanding atomic structure, significantly transforming chemistry.
Importance of Organic Chemistry
- Organic chemistry focuses on the study of carbon compounds, a unique element due to its ability to form diverse bonds and structures.
- Carbon's electronic structure allows it to form four strong covalent bonds and create extensive chains and rings essential for organic compounds.
Atomic Structure and Electron Configuration
- Atoms consist of protons and neutrons in the nucleus, with electrons occupying orbitals.
- The lack of charge balance is established by equal numbers of protons and electrons.
- Isotopes are variations of elements with the same atomic number but different mass numbers.
- Orbitals (s, p, d, f) are regions around the nucleus where electrons are likely to be found, structured across different energy levels.
Isomerism
- Molecules can be arranged differently despite consisting of the same atoms, leading to isomerism.
- The three-dimensional nature of molecules influences their properties and functional behavior in organic chemistry.
