1.	Lithium hydride can be used to prepare other useful hydrides . Beryllium hydride is one of them . Suggest a route for the preparation of beryllium hydride starting from lithium hydride . Write chemical equations involved in the process .
Answer» Solution :`BeH_(2)` cannot be PREPARED directly by heating POWDERED beryllium with dihydrogen . It can , however , be prepared from the corresponding halides by reduction with complex alkali metal hydrides such as lithium aluminium hydride as follows . `8 LiH + Al_(2) Cl_(6) to 2 LiAlH_(4) + 6 LiCl` `2 BeCl_(2) + LiAlH_(4) to 2 BeH_(2) + LiCl + AlCl_(3)`.
