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.

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. WebThe reaction mechanism for reducing aldehydes and ketones are exactly the same. Let's look at an example of an aldehyde being reduced lithium-aluminum hydride then water. … eastern shore ship print connectWebAldehydes 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. cui yi stanford university

"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. Most common … " - Reactivity of aldehyde and ketone
