Web• Learn the major chemical reaction of aldehydes and ketones, and learn how to predict the products of hydrogenation, oxidation, and addition of alcohol reactions. • Learn to recognize the acetal, hemiacetal, ketal, and hemiketal group, and how these are related to aldehydes and ketones. Chapter 4 Aldehydes and Ketones The Carbonyl Group 2 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 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. WebAldehydes react with alcohols to produce hemiacetals in a manner very similar to the reaction of aldehydes with water to produce hydrates. (Ketones react in identical fashion, …
WebJan 23, 2024 · Aldehydes and ketones can be converted into 1°, 2° and 3° amines using reductive amination. The reaction takes place in two parts.
