Naming Aldehydes. For example, H 2 C=O is methanal, more commonly called formaldehyde.Since an aldehyde carbonyl group must always lie at the end of a carbon chain, it is always is given the #1 location position in numbering and it is not necessary to include it in the name. Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4-dicarbonyls. The IUPAC system of nomenclature assigns a characteristic suffix -al to aldehydes. Most aldehydes and ketones react with 2º-amines to give products known as enamines. The remaining two bonds are to other carbon atoms or hydrocarbon radicals. Formaldehyde is the simplest aldehyde whereas acetone is the smallest ketone. This compound has the carbonyl group on an interior carbon atom, so it is a ketone. With the exception of unsubstituted hydrazones, these derivatives are easily prepared and are often crystalline solids - even when the parent aldehyde or ketone is a liquid. Alcohol - Alcohol - Structure and classification of alcohols: Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Si l'un des atomes de carbone lié à l'atome d'azote (N) fait partie d'un groupe carbonyle, la molécule appartient à la famille des amides. 1) showed characteristics absorption bands at 3500 (–NH stretching), 1590 (C=O stretching), 3000 (aromatic –CH stretching), and 1250 cm −1 (ether stretching).
