Study Notes
The Vital Force Theory and Its Rejection
- The vital force theory stated that organic compounds could only be manufactured by and within living things.
- The theory proposed that organic compounds had a non-physical, vital force that differentiated them from inorganic compounds.
Friedrick Wohler's Breakthrough
- Friedrick Wohler rejected the vital force theory by synthesizing urea from inorganic materials.
- Wohler synthesized urea (NH2)2CO, an organic compound found in the urine of mammals, from ammonium cyanate (NH4CNO), a substance of known inorganic origin.
Significance of Wohler's Synthesis
- Wohler's synthesis of urea disproved the vital force theory's explanation for the origin of organic compounds.
- The synthesis demonstrated that organic compounds could be manufactured from inorganic materials, outside of living things.
Characteristics of Organic Compounds
- Organic compounds typically contain carbon and hydrogen, as well as other elements such as oxygen, nitrogen, and sulfur.
- For historical and conventional reasons, certain carbon compounds like carbonates, cyanides, and carbides are studied as inorganic compounds.
Definition of Organic Chemistry
- According to the modern definition, organic chemistry deals with the study of compounds of carbon and hydrogen, and their derivatives.
- Derivatives of carbon and hydrogen compounds include molecules that contain additional elements or functional groups.
