WebCarboxylic acids, acid halides, esters, and amides are easily reduced by strong reducing agents, such as lithium aluminum hydride (LiAlH 4 ). The carboxylic acids, acid halides, and esters are reduced to alcohols, while the amide derivative is reduced to an amine. Most reductions of carboxylic acids lead to the formation of primary alcohols.
