Question

What is the formula of urea?

• A. NH$_2$CONH$_2$
• B. NH$_4$HSO$_4$
• C. C$_2$H$_5$OH
• D. NH$_4$OH

Answer 1

The Correct Option is A

Urea is an organic compound with a carbonyl group (C=O) and two amine groups (NH$_2$).$\\$So, The correct answer is NH$_2$CONH$_2$ .

Answer 2

Urea is an important organic compound that contains a carbonyl group (C=O) and two amine groups (NH₂). Its chemical structure can be represented as NH₂CONH₂, where the carbonyl group (C=O) is bonded to two amine groups, each containing nitrogen and hydrogen atoms. This structure makes urea a vital compound in biological systems, particularly in the urea cycle in animals for nitrogen waste excretion.

Urea is widely used in the agricultural industry as a nitrogen-rich fertilizer. It is also an important component in various industrial applications, such as the production of plastics, resins, and pharmaceuticals. The simplicity and versatility of its structure make urea a key molecule in both biological and industrial chemistry.

So, the correct chemical formula for urea is NH₂CONH₂.
