  1. Explain the significance of Wohler’s synthesis of urea from ammonium cyanate. Include in your explanation the distinction between vitalism and biochemistry.

Solutions

Expert Solution

The Wohler synthesis is of great historical significance because for the first time an organic compound was produced from inorganic reactants. This finding went against the mainstream theory of that time called vitalism which stated that organic matter possessed a special force or vital force inherent to all things living. For this reason a sharp boundary existed between organic and inorganic compounds. Urea was discovered in 1799 and could until then only be obtained from biological sources such as urine.

It is argued that organic chemistry did not actually start with this discovery in 1828 but 4 years earlier with the synthesis of oxalic acid in 1824 also by Wöhler and also from the inorganic precursor cyanogen. It is also argued that vitalism was not put to bed either in 1828. His contemporaries Liebig and Pasteur never abandoned vitalism and it took until 1845 when Kolbe repeated an inorganic – organic conversion of carbon disulfide to acetic acid before vitalism started to lose supporters in serious numbers.
