Urea was first synthesized by Wohler from an inorganic material named:
Correct answer: D. Ammonium cyanate
- A. Ammonium bicarbonate
- B. Ammonium nitrate
- C. Ammonium oxalate
- D. Ammonium cyanate
- E. Ammonium chloride
Explanation
Urea was synthesized by Friedrich Wöhler in 1828 using ammonium cyanate. This synthesis was significant because it demonstrated that organic compounds could be created from inorganic materials, which contradicted the prevailing belief in 'vitalism' - the idea that organic compounds could only be produced by living organisms. The other options, such as ammonium bicarbonate, ammonium nitrate, ammonium oxalate, and ammonium chloride, were not involved in Wöhler's synthesis of urea.

About Fundamental Principles of Organic Chemistry
Organic chemistry begins with carbon compounds classified by carbon skeleton, saturation and functional group. Work includes identifying groups such as hydroxyl, carbonyl, carboxyl and amino, applying basic nomenclature, and distinguishing structural, geometric and optical isomers, where the same molecular formula does not necessarily mean the same structure or properties.
