  4. D \(\mathrm{LiNH}_{2}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(\mathrm{Li}_{2} \mathrm{NH}\)

Step-by-step Solution

Detailed explanation

Lithium imide is an inorganic compound with the chemical formula Li 2NH. This white solid can be formed by a reaction between lithium amide and lithium hydride. LiNH2 + LiH ? Li2NH + H2 The product is light-sensitive and can undergo disproportionation to form lithium nitride, which is characteristically red.
