Designing a Synthesis

Organic synthesis is a branch of chemical synthesis that involves the planned construction of organic compounds/molecules from smaller units that possess functional groups. Friedrich Wöhler was the first scientist who designed the synthesis of an organic compound, urea from inorganic starting materials silver cyanate with ammonium chloride via a simple, one-step synthesis.
