Web4 sep. 2024 · The lithium tri-tert-butoxyaluminum hydride that the first student used is a milder reagent than LAH and will stop reacting at the aldehyde. The LAH that the second student used is much more reactive and will continue to reduce the benzoic acid as far as possible, going all the way to the alcohol. See the attachment for the reaction steps.

Webidentify lithium aluminum hydride as a reagent for reducing acid halides to primary alcohols, and explain the limited practical value of this reaction. identify the partial reduction of an acid halide using lithium tri‑tert‑butoxyaluminum to form an aldehyde. WebLiAlH 4 also known as lithium aluminum hydride or LAH, is a strong reducing agent meaning it will create less bonds to oxygen (more bonds to hydrogen). Commonly seen is its use on carbonyls such as carboxylic acid, esters, and amides. For now all you really need to know is that LiAlH 4 is going to add H’s to many types of molecules.
