Question

Ammonia is not a product in the:
A. Hydrolysis of nitrolim
B. Hydrolysis of Aluminium nitride
C. Decomposition of ammonium nitrite
D. Hydrolysis of urea.

Answer 1

The molecular formula of ammonia is $N{{H}_{3}}$ . The molecular formula of nitrolim is $CaC{{N}_{2}}$ .
The molecular formula of aluminum nitride is AlN. The molecular formula of ammonium nitrite is $N{{H}_{4}}N{{O}_{2}}$ . The molecular formula of urea is $N{{H}_{2}}CON{{H}_{2}}$ .

Complete step by step answer:
- In the question it is asked to find that ammonia should not be released as a product from the given options.
- We have to find which option ammonia is not going to be released.
- Coming to the given options, option A, Hydrolysis of nitrolim. The hydrolysis of nitrolim chemical reaction is as follows.
$CaC{{N}_{2}}+3{{H}_{2}}O\to CaC{{O}_{3}}+2N{{H}_{3}}$
- Up on hydrolysis nitrolim produces ammonia gas as the product. So, option A wrong.

- Coming to option B, Hydrolysis of Aluminium nitride. The hydrolysis of Aluminium nitride is as follows.
$AlN+3{{H}_{2}}O\to Al{{(OH)}_{3}}+N{{H}_{3}}$
- Up on hydrolysis Aluminium nitride produces aluminium trihydroxide and ammonia as the products. So, option B is also wrong.

- Coming to option C, Decomposition of ammonium nitrite. The decomposition of ammonium nitrite is as follows.
$N{{H}_{4}}N{{O}_{2}}\xrightarrow{\Delta }{{N}_{2}}+2{{H}_{2}}O$
- On heating ammonium nitrite decomposes and produces nitrogen and water molecules as the products. Means there is no ammonia gas released during decomposition of ammonium nitrite. So, the correct option is B.

- Coming to option D, Hydrolysis of urea. Hydrolysis of urea is as follows.
$N{{H}_{2}}CON{{H}_{2}}+{{H}_{2}}O\to C{{O}_{2}}+2N{{H}_{3}}$
- On hydrolysis urea produces ammonia and carbon dioxide as the products. So, option D is also wrong.
So, the correct answer is “Option C”.

Note: Ammonia is a good fertilizer to the crops. Plants or trees cannot digest nitrogen which is available in the atmosphere because the nitrogen atoms in nitrogen molecules are bonded together with triple bonds. It is very difficult to break the triple bond by the plants. That is why ammonia should be supplied to crops as a nitrogen source.
