Which of the following formula represents lithium imide?
- A \(\mathrm{L} \mathrm{i}_{3} \mathrm{~N}\)
- B \(\mathrm{LiNH}_{2}\)
- C \(\mathrm{Li}_{2} \mathrm{NH}\)
- D LiNH
Answer & Solution
Correct Answer
(C) \(\mathrm{Li}_{2} \mathrm{NH}\)
Step-by-step Solution
Detailed explanation
\(\mathbf{L i}_{2} \mathrm{NH}\)
The inorganic compound lithium imide has the chemical formula NH. A reaction between lithium amide and lithium hydride can produce this whitish substance.
\(\mathrm{LiH}_{2}+\mathrm{LiH} \longrightarrow \mathrm{Li}_{2} \mathrm{NH}+\mathrm{H}_{2}\)
Lithium Imlde
The product is sensitive to light and can be disproportionated to generate lithium nitride.
