Abstract: The reaction of amines with aldehydes and ketones has been exploited for over 150 years to produce Schiff bases, one of the most popular classes of compounds in both organic and coordination chemistry. In certain cases, however, compounds other than
In this reaction, an aldehyde is oxidized to a carboxylic acid while the Ag1+ is reduced to silver metal, which deposits as a thin film on the inner surface of the glass or the formation of a “silver mirror”.(Tollens’ Test) A negative result in this test indicates that the solution is a ketone. (Identification of aldehydes and ketones) This
Chapter 19. Aldehydes and Ketones: Nucleophilic Addition Reactions Based on McMurry’s Organic Chemistry, 6th edition. 2 Aldehydes and Ketones Aldehydes and ketones are characterized by the the carbonyl functional group (C=O) The compounds occur widely in nature as intermediates in metabolism and biosynthesis They are also common as chemicals, as solvents, monomers, adhesives, agrichemicals

29.1.4 Reactions of Aldehydes and Ketones If you examine the structure of a molecule of the carbonyl compound, you will find that there are three centres of reactivity in it as shown below : 223 Aldehydes, Ketones and Carboxylic Acids MODULE – 7 Notes Chemistry of Organic Compounds Since the oxygen atom isnucleophilicin nature, it is attacked by theelectrophiles, whereas the carbonyl carbon is
The reactivity of ketones is essentially determined by the dipolar nature of the carbonyl group, thus it is shared with aldehydes. One of the main differences between the reactivity of aldehydes and ketones is that the ketones do not undergo to oxidation reactions, while aldehydes can oxidize to carboxylic acids.

Aldehydes and Ketones I: Electrophilicity and Oxidation—Reduction Conclusion. In this chapter, we have examined the properties of aldehydes and ketones. Specifically, we have taken a look at the reactivity of the carbonyl carbon in nucleophilic addition reactions and examined how aldehydes and ketones can be oxidized and reduced. Carbonyls
In this lesson we will look at reactions that aldehydes and ketones under-go. These reaction include oxidation into carboxylic acids, reduction into alcohols, and forming cyanohydrin.

This is the reaction of a-haloester, usually an a-bromoester with an aldehyde or ketone in the presence of Zinc metal to produce b-hydroxyester. e) Pinacol-pinacolone Rearrangement The acid catalysed rearrangement of 1,2 diols (Vicinal diols) to aldehydes or ketones with the elimination of water is known as pinacol pinacolone rearrangement.
