Urea is the most widely used nitrogen fertilizer in Pakistan. Its composition is:
Correct answer: D. N2H4CO
- A. NH2CO
- B. N2H5CO2
- C. N2H4CO2
- D. N2H4CO
Explanation
Urea, also known as carbamide, is an organic compound with the chemical formula CO(NH2)2. This amide has two -NH2 groups joined by a carbonyl (C=O) functional group.The composition of urea, which is the most widely used nitrogen fertilizer in Pakistan, is N2H4CO.Urea has the chemical formula CO(NH2)2, which can also be represented as NH2CONH2. This indicates that urea consists of two amine groups (NH2) attached to a carbonyl group (C=O). The structure of urea is shown as N2H4CO, representing the arrangement of atoms.
