Question

Which of the following formula represents lithium imide?

Options

• LiNH₂

• Li₂NH

• Li₃N

• LiNH

Answer 1

Li₂NH

Explanation:

The inorganic compound lithium imide has the chemical formula NH. A reaction between lithium amide and lithium hydride can produce this whitish substance.

\[\ce{LiH2 + LiH -> \underset{\text{Lithium lmlde}}{Li2NH + H2}}\]

The product is sensitive to light and can be disproportionated to generate lithium nitride.
