What is a Lithium Aluminium Hydride (LiAlH₄)?

Lithium Aluminium Hydride (LiAlH₄) is a compound composed of lithium (Li), aluminium (Al), and hydrogen (H). It is a powerful reducing agent widely used in organic chemistry, particularly for reduction reactions involving alcohols, esters, ketones, and carboxylic acids. LiAlH₄ reacts violently with water or moisture, releasing flammable hydrogen gas, which requires careful handling.

Lithium aluminium hydride is highly valuable in industrial chemical synthesis, especially as a strong reducing agent in organic synthesis. It plays a crucial role in reducing aldehydes and ketones to alcohols, as well as reducing carbon-oxygen bonds and opening epoxides. Additionally, it has been studied for its potential in energy storage, fuel cells, and hydrogen generation technologies, thanks to its high hydrogen release capabilities, making it a promising candidate for sustainable energy solutions.
