WebAldehydes produce 1º-alcohols and ketones produce 2º-alcohols. In metal hydrides reductions the resulting alkoxide salts are insoluble and need to be hydrolyzed (with care) before the alcohol product can be isolated. In the sodium borohydride reduction the methanol solvent system achieves this hydrolysis automatically.

WebChemical Compounds Nucleophilic addition. Both aldehydes and ketones undergo many of these reactions, although aldehydes are usually much more reactive, for two reasons. First, it is easier for a nucleophile to approach the positive carbon atom of an aldehyde molecule, which always has one bond attached to the small hydrogen atom. WebAldehydes and ketones react to yellow, orange, or reddish-orange precipitates with the 2,4-dinitrophenylhydrazine reagent, whereas alcohols do not react. This is a successful technique for checking for the existence of a drug or demonstrating its absence.

WebA few drops of the aldehyde or ketone are added to the reagent, and the mixture is warmed gently in a hot water bath for a few minutes. Aldehydes reduce the complexed copper (II) ion to copper (I) oxide. Because the solution is alkaline, the aldehyde itself is oxidised to a salt of the corresponding carboxylic acid.

WebAldehydes and ketones are excellent electrophiles due to the high δ+ charge on the carbon atom of C=O group. Thus, they react readily with many nucleophiles.
