The first organic compound prepared in the laboratory was:
Correct answer: B. Urea
- A. Peat
- B. Urea
- C. Sugar
- D. Alcohol
Explanation
The first organic compound prepared in the laboratory was urea. Urea was synthesized by Friedrich Wöhler in 1828 from inorganic starting materials (ammonium chloride and silver cyanate). This experiment is considered a landmark in the history of chemistry because it showed that organic compounds, which were believed to be produced only by living organisms, could also be synthesized from inorganic substances. Therefore, option b is correct.

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.
