Friedrich Wöhler prepared urea from:
Correct answer: C. Ammonium cyanate
- A. Amino acids
- B. Ammonium carbonate
- C. Ammonium cyanate
- D. Xanthin
Explanation
Friedrich Wöhler prepared urea from ammonium cyanate, an inorganic compound. This challenged the belief of vitalism, which held that organic compounds could only be produced by living organisms. Wöhler's synthesis of urea demonstrated that organic compounds could be created through purely chemical processes, marking a significant moment in the history of chemistry.

About Classification of Organic Compounds
Organic compounds are classified by carbon skeleton into open-chain, branched-chain and cyclic compounds, including homocyclic and heterocyclic types. The classification also uses functional groups to distinguish hydrocarbons, halo compounds, alcohols, aldehydes, ketones, carboxylic acids and their derivatives, which is different from naming compounds by IUPAC rules.
