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 :Beryllium hydride cannot be prepared directly by REACTION with `H_(2)`. It is prepared by REACTING with `LiAlH_(4)`. Following REACTIONS take PLACE : `8LiH+Al_(2)Cl_(6) to 2LiAlH_(4) +6LiCl` `2BeCl_(2) +LiAlH_(4) to 2BeH_(2)+LiCl +AlCl_(3)`
