The carboxylic acid derivatives are a family of closely related functional groups: . Diborane Reduction. For most carboxylic acid derivatives (such as esters), the resonance form is only a minor contributor and so the real "picture" looks very close to the carbonyl Lewis structure.

Catalytic Reduction. Different carboxylic acid derivatives have very different reactivities, acyl chlorides and bromides being the most reactive and amides the least reactive, as noted in the following qualitatively ordered list. ).Carboxylic acids are the most acidic of the common organic functional groups.

From propene, to make propanol, just do an anti-Markovnikov H 2 O addition using borane (BH 3 or B 2 H 6) then hydrogen peroxide (H 2 O 2).
