Lithium aluminium hydride, commonly abbreviated to LAH, is an inorganic compound with the chemical formula Li[AlH4] or LiAlH4. It is a white solid, discovered by Finholt, Bond and Schlesinger in 1947. This compound is used as a reducing agent in organic synthesis, especially for the reduction of esters, carboxylic acids, and amides. The solid is dangerously reactive toward water, releasing gaseous hydrogen (H2). Some related derivatives have been discussed for hydr… WebCarboxylic acids can be converted to 1 o alcohols using Lithium aluminum hydride (LiAlH 4 ). Note that NaBH 4 is not strong enough to convert carboxylic acids or esters to alcohols. An aldehyde is produced as an intermediate during this reaction, but it cannot be isolated because it is more reactive than the original carboxylic acid. read flipped free onlineWebStructure of Lithium Aluminium Hydride – LiAlH 4. In aluminium hydride, AlH 4 – ion, hydrogens are arranged in a tetrahedral arrangement around Al 3+. The coordination of hydride, H – ions to Al 3+ ions results in its formation. Li + centres are surrounded by five AlH 4 – tetrahedra in the structure. read flowset
