Question

one reaction for the synthesis of lithium aluminum hydride​

Answer 1

Explanation:

LiAlH4 was first prepared from the reaction between lithium hydride (LiH) and aluminium chloride:[4][5]

i) 4 LiH + AlCl3 → LiAlH4 + 3 LiCl

In addition to this method, the industrial synthesis entails the initial preparation of sodium aluminium hydride from the elements under high pressure and temperature.

II) Na + Al + 2 H2 → NaAlH4

LiAlH4 is then prepared by a salt metathesis reaction.

III) NaAlH4 + LiCl → LiAlH4 + NaCl

which proceeds in a high yield. LiCl is removed by filtration from an ethereal solution of LAH.

any one of these
