First organic compound synthesized in laboratory was _________________?
Correct answer: D. urea
- A. tartaric acid
- B. ethyl alcohol
- C. methanol
- D. urea
Explanation
Wöhler prepared urea in the laboratory in 1828 by heating ammonium cyanate, showing that an organic compound could be made from an inorganic salt. Ethyl alcohol may be chosen because it is an organic compound, but it was not the first one associated with disproving vitalism.

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.
