Study Notes
Organic Chemistry
- The study of hydrocarbons and their derivatives
- Vital force theory (Berzelius 1815): Organic compounds are only prepared from living matter and cannot be prepared in a lab.
- Disproving vital force theory: In 1828, Friedrich Wöhler prepared urea in the lab, forming urea from inorganic materials.
Characteristics of Organic Compounds
- Unique nature of carbon atoms
- Millions of organic compounds are known
- Carbon atoms exhibit a unique self-linking property
- Self-linking property: The ability of carbon atoms to bond to themselves and other atoms
- Carbon forms long chains, branched chains, and rings
- Forms stable single and multiple bonds with others atoms like nitrogen, oxygen, sulfur, hydrogen, and phosphorus.
Specific Examples
- NaCN (Metal Cyanide): R-C
- N(H)4 C(N)O (Metal
- KSCN (Metal Thiocyanate): R-CN
- CS₂ (Carbon disulfide): These are not organic
- CO2 (Carbon Dioxide)
- CO (Carbon Monoxide)
- Na₂CO₃ (Metal Carbonate)
- NaHCO₃ (Metal Bicarbonate)
- Na₂SO₄ (Metal Sulfate)
