Question

The first organic compound urea was synthesized in laboratory from which one of the following compound?

• A. Ammonium chloride
• B. Ammonium cyanate
• C. Ammonium carbonate
• D. None of the above

Answer 1

The correct option is B Ammonium cyanate

The first organic compound synthesized in laboratory was urea.
It was prepared from Ammonium Cyanate.
$N{H}_4^{+}CN{O}^{-}\stackrel{\Delta }{\to }N{H}_{2}CON{H}_2\left(\text{Ammonium Cyanate}\right)\left(\text{Urea}\right)$


Theory :

Wohler Theory- Wohler converted inorganic compound ammonium cyanate found from non- living matters into urea an organic compound, by heating it, in 1828.
First organic compound synthesized in laboratory is Urea.
These are compounds of carbon, hydrogen and their derivatives.The study of these compounds are done in a separate branch of chemistry called Organic Chemistry.
