Why lithium is least reactive but the strongest reducing agent?

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. WebIn the lithium aluminium hydride reduction water is usually added in a second step. The lithium, sodium, boron and aluminium end up as soluble inorganic salts at the end of either reaction. Note! LiAlH 4 and NaBH 4 are both capable of reducing aldehydes and ketones to the corresponding alcohol. Examples Mechanism evaluating recommendation一周了
