Study Notes
Organic Chemistry: A Branch of Chemistry
- Organic chemistry focuses on compounds containing carbon and hydrogen, forming hydrocarbons and their derivatives, where carbon is the essential element.
- The study of organic compounds includes understanding their structural, condensed, and molecular formulas to represent their composition and arrangement.
- Historically, the term "organic" referred to substances found in living organisms due to the "vital force" theory, which suggested they couldn't be synthesized artificially.
- However, the theory was disproven when scientists like Wohler synthesized urea from inorganic materials, and Kolbe produced acetic acid in a laboratory.
- Today, the definition has changed to focus on carbon-based compounds, encompassing a vast range of substances like carbohydrates, proteins, lipids, and polymers.
- Some examples include pharmaceuticals, pesticides, plastics, and synthetic fibers, highlighting the diverse applications of organic chemistry.
Key Facts About Organic Compounds
- Molecular Formula: Represents the actual number of atoms in a molecule, like C4H10 for butane.
- Structural Formula: Shows the precise arrangement of atoms in a molecule, indicating single, double, and triple bonds.
- Condensed Formula: Highlights the groups of atoms attached to each carbon atom in a chain.
- Electronic or Dot and Cross Formula: Depicts the sharing of electrons between atoms in the molecular structure.
Breaking the Vital Force Theory
- Wohler's synthesis of urea in 1828 proved that organic compounds could be made from inorganic substances, defying the theory that only living organisms could produce them.
- Kolbe's subsequent synthesis of acetic acid in 1845 further solidified this disproof.
- This led to a shift in understanding the origins of organic compounds and paved the way for modern organic chemistry, which focuses on the properties and reactions of carbon-containing compounds.
