Question

Wohler’s synthesis is used for the preparation of:
A.Glycine
B.Amino acids
C.Urea
D.Proteins

Answer 1

The synthesis of urea from cyanic acid and ammonia through the intermediate of ammonium cyanate is known as Wohler’s synthesis. It is an artificial method to produce urea from inorganic compounds.

Complete step by step answer:
Wohler’s synthesis is basically an artificial method to produce urea. The main reagent used to initiate this synthesis is ammonium cyanate which forms the combination of cyanic acid and ammonia.
The conversion of ammonium cyanate into urea is as following:
$N{H_4}(NCO) \to N{H_3} + HNCO \to {(N{H_2})_2}CO$
We can see that the reaction starts $N{H_4}(NCO)$ which dissociates into ammonia and cyanic acid and then further both of these combine and form urea.
So basically Wohler’s synthesis is used for the preparation of urea $(N{H_2}CON{H_2})$ .

Hence, option (C) is correct.

Additional information: Friedrich Wohler, the inventor of Wohler’s synthesis is the father of modern organic chemistry. He was simply trying to make ammonium cyanate but he ended up with the formation of urea, and from this moment there was the evolution of organic chemistry which we are studying today.

Note:
In the time of $1800's$ it was thought that urea can only be obtained from living organisms, but a German scientist made a notable discovery of urea from inorganic compounds, this process of urea synthesis was named as Wohler’s synthesis.
