Answer:

As Reducing Agent

Explanation:

Use in organic chemistry

Lithium aluminium hydride (LiAlH4) is widely used in organic chemistry as a reducing agent. It is more powerful than the related reagent sodium borohydride owing to the weaker Al-H bond compared to the B-H bond.

The role of LiAlH_{4} in organic synthesis is as (b) a reducing agent.

  • LiAlH_{4} is a strong, unselective reducing agent for polar double bonds.
  • It is one of the most readily available sources of H^- or hydrogen anion.  
  • It can easily reduce aldehydes, ketones, esters, carboxylic acid chlorides, carboxylic acids and even carboxylate salts to alcohols.
  • Whereas the amides and nitriles are reduced to amines.
  • It is more powerful than the related reagent sodium borohydride owing to the weaker Al-H bond compared to the B-H bond.
