2,4-Dinitrophenylhydrazine : Aldehydes and ketones react with 2,4-dinitrophenylhydrazine reagent to form yellow, orange, or reddish-orange precipitates, whereas alcohols do not react. Formation of a precipitate therefore indicates the presence of an aldehyde or ketone. The precipitate from this test also serves as a solid derivative.

Oxidation Reactions of Sugars

Aldehydes are much easier to oxidize than ketones. The oxidizing agents Ag+, Cu+2, and K 2CrO 4 can transform an aldehyde to a carboxylic acid. The carbonyl carbon is oxidized by 2 electrons from the I to the III oxidation state. Silver metal is …

Carboxylic Acid Structure and Chemistry

amines, alcohols, phenols, aldehydes, ketones, esters, amides and isosteric compounds. Carboxylic acids have a greater number of dipoles and stronger dipoles than these other organic compounds, and thus can form more and stronger H-bonds with other substances capable of H-bonding interactions. The dipolar nature of these other organic functional
