lithium aluminum hydride
Quick Summary
Lithium aluminum hydride (LiAlH₄) is a white, flammable solid that is soluble in ether. It is synthesized by reacting lithium hydride (LiH) with anhydrous aluminum chloride.1
LiAlH₄ is a powerful reducing agent, particularly for organic compounds, capable of converting carboxylic acids into alcohols. It is classified as a complex saline hydride, a type of hydride compound where hydrogen exists as a negatively charged ion (H⁻). These compounds are strong bases and react readily with water, releasing hydrogen gas. Lithium hydride (LiH) itself is a flammable crystalline solid used as a source of hydrogen and in the synthesis of other lithium compounds, including lithium aluminum hydride.123
