- $\mathrm{LiNO_3}$
- $\mathrm{Li_2NH}$
- $\mathrm{Li_3N}$
- $\mathrm{LiNH_2}$
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Understanding imide ion.
Imide ion has the formula $\mathrm{NH^{2-}}$. It contains nitrogen bonded to one hydrogen atom with a charge of $-2$.
Step 2: Charge balance with lithium.
Lithium forms $\mathrm{Li^+}$ ions. Two lithium ions are required to balance the $-2$ charge of the imide ion.
Step 3: Formation of lithium imide.
Combining two $\mathrm{Li^+}$ ions with one $\mathrm{NH^{2-}}$ ion gives the formula $\mathrm{Li_2NH}$.
Step 4: Conclusion.
Hence, the correct formula of lithium imide is $\mathrm{Li_2NH$}.
