  1. $NH _{ 2 }CONH _{ 2 }\longrightarrow HNCO+NH _{ 3 }$

  2. $N{ H } _{ 2 }CON{ H } _{ 2 }+{ H } _{ 2 }O\longrightarrow 2N{ H } _{ 3 }+C{ O } _{ 2 }$

  3. $2NH _{ 2 }CONH _{ 2 }\longrightarrow H _{ 2 }NCONHCONH _{ 2 }+NH _{ 3 }$

  4. Both 1 and 2

Show answer
Correct Option: B
Explanation:

Urea is a major fertilizer used worldwide. It provides nitrogen to the soil by decomposing to ammonia and $CO _2$ when acted on by urease, an enzyme in soils. Then, ammonia is taken by the plants.


$N{ H } _{ 2 }CON{ H } _{ 2 }+{ H } _{ 2 }O\longrightarrow 2N{ H } _{ 3 }+C{ O } _{ 2 }$

Hence the correct option is B.
