An ionic hydride of an alkali metal has significant covalent character and is almost unreactive towards oxygen and chlorine . This is used in the synthesisi of other useful hydrides. Write the formula of this is used in the synthesis of other hydrides. Write the formula of this hydride. Write its reaction with `Al_(2)Cl_(6)`.

Answer

N/a

Explanation

It is LiH because it has significant covalent character due to the smallest alkali metal, Li LiH is very statble. It is almost unreactibve towards oxygen and chlorine.
It reacts with `Al_(2)Cl_(2)` to from lithium aluminium hydride.
`8LiH + Al_(2)Cl_(6) to 2LiAIH_(4) to 6LiCI`
