Question
Which of the components are used to prepare fertilizers like urea from the following?
- Carbon dioxide and nitrogen
- Carbon dioxide and nitrogen
- Only carbon dioxide
- Carbon dioxide and hydrogen
Hint:
Urea has an amide functional group. Urea is a diamide of carbonic acid. When both hydroxyl groups of carbonic acid are replaced with ammonia groups, the formed structure is known as an amide. The structure or constitution of the product gives the idea about reactants.
The correct answer is: Carbon dioxide and nitrogen
Carbon dioxide and nitrogen are used to prepare fertilizers like urea.
