Lithium aluminium hydride can be prepared from the reaction of
Options
- ALiCl and Al 2 H 6
- BLiH and Al 2 Cl 6
- CLiCl , Al and H 2
- DLiH and Al OH 3
Correct answer
B. LiH and Al 2 Cl 6
Step-by-step solution
Lithium aluminium hydride can be prepared by the reaction of dimer of aluminium trichloride and lithium hydride by the below reaction with a high yield: 8 LiH + Al 2 Cl 6 ⟶ 2 LiAlH 4 + 6 LiCl Lithium aluminium hydride is extensively used for reduction of organic compounds.
