Question

Philoid · Accepted Answer

The ionic hydride of an alkali metal which has a significant covalent character and is almost unreactive towards oxygen and chlorine at moderate temperatures is Lithium hydride (LiH).

It is therefore used in synthesis of other useful hydrides.

Reaction of LiH with Al₂Cl₆ is- 8LiH + Al₂Cl₆→ 2LiAlH₄ + 6LiCl

In this way LiH was useful in preparation of LiAlH₄ which is an important hydride (often used as reducing agent in many organic reactions).

An ionic hydride of an alkali metal has significant covalent character and is almost unreactive towards oxygen and chlorine. This is used in the synthesis of other useful hydrides. Write the formula of this hydride. Write its reaction with Al2Cl6.
