Question

First organic compound prepared from inorganic compound was:
A.Acetic acid
B.Methane
C.Urea
D.Ethyl alcohol

Answer 1

Organic compounds will have a carbon atom. Inorganic compounds do not have a carbon. First organic compound from an inorganic compound was discovered by Wohler.

Complete step by step answer:
Organic compounds are those which have a carbon atom and inorganic compounds are those which do not have carbon. Urea is the first organic molecule prepared from an inorganic molecule. Urea has the molecular formula $C{H_4}{N_2}O$ and has a molar mass of 60.06 g/mol.
Urea was discovered by the scientist Wohler in 1828. It was prepared from silver cyanate and ammonium chloride. These are two inorganic compounds.
The equation for the formation of urea is given below:
$NH3 + CO2\overset {} \leftrightarrows NH2COONH4$
Hence the correct answer is C.

Additional information:
Urea is an organic compound. It is also known as carbamide, carbonyl amine, Diamino methanal, Carbonyl diamide etc. It is a combination of ammonia and carbon dioxide. Urea is a neutral compound. When it is dissolved in water, it shows neither acidic or basic character. But it can increase the pH of the aqueous solution. A high concentration of urea can reduce the activity of hydrogen. But it will not affect the activity of the other substance. Urea has two -NH2 groups. The functional group present in urea is carbonyl. Urea serves an important role in the metabolism of nitrogen containing substances.

Note: Organic compounds are characterised by the carbon-hydrogen bonds. The application of urea is used as a fertilizer. Urea form some resins. It is also used in vehicles for reducing air pollution from diesel engines. Urea is known as a keratolytic. It is the most important product of protein degradation. Urea is rapidly hydrolysed to ammonia and carbon dioxide.
