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 .
Since the ionic hydride of alkali metal has a significant covalent character, it is LiH. Since LiH is very stable, it is almost unreactive towards O2 and Cl2. It reacts with Al2Cl6? form lithium aluminium hydride.
