Aldehydes and ketones can be reduced not only to alcohols but also to alkanes. Some reactions for this transformation include the Clemmensen reduction (in strongly acidic conditions) and the Wolff-Kishner reduction (in strongly basic conditions), as well as the various modifications of the Wolff-Kishner reaction.

Aldehydes and ketones are organic molecules with a carbonyl group. In a carbonyl group, carbon atom has a double bond to oxygen. The carbonyl carbon atom is sp 2 hybridized. So, aldehydes and ketones have a trigonal planar arrangement around the carbonyl carbon atom.
Derivatives of imines that form stable compounds with aldehydes and ketones include phenylhydrazine, 2,4‐dinitrophenylhydrazine, hydroxylamine, and semicarbazide. Aldehydes and Ketones are often called as methanoyl or formyl group. The carbon atom of this group has 2 remaining bonds that might be occupied by aryl or alkyl or substituents. If neither of these substituents is hydrogen, the compound is a Ketone. Aldehydes and ketones play an important role in the chemistry of carbohydrates. The term carbohydrate literally means a "hydrate" of carbon, and was introduced to describe a family of compounds with the empirical formula CH 2 O. Glucose and fructose, for example, are carbohydrates with the formula C 6 H 12 O 6 .
Figure 8. Infrared Spectrum of 2-Butanone. Aldehyde. In the IR spectra of an aldehyde, a peak usually appears around 2720 cm-1 and often appears as a shoulder-type peak just to the right of the alkyl C–H stretches. H–C=O stretch 2830
Aldehyde & Ketone Aldehydes, and ketones are important carbonyl compounds (a compound that bears a C=O group) for organic synthesis because they can readily be oxidized, or reduced into other chemical materials. Aldol condensations are important in organic synthesis, because they provide a good way to form carbon–carbon bonds. For example, the Robinson annulation reaction sequence features an aldol condensation; the Wieland–Miescher ketone product is an important starting material for many organic syntheses.

When and aldehyde or ketone is present in a molecule which also contains an alcohol functional group the carbonyl is given nomenclature priority by the IUPAC system. This means that the carbonyl is given the lowest possible location number and the appropriate nomenclature suffix is included.
Chapter 21. 257. 23.1 Mechanism of Carbonyl Condensation Reactions. An enolate of one carbonyl The aldehyde that is the product is very easily oxidized to a carboxylic to the more stable ketone. Under acidic conditions an aldehyde or ketone will react. Aldehyd.
2021-04-13 · You will remember that the difference between an aldehyde and a ketone is the presence of a hydrogen atom attached to the carbon-oxygen double bond in the aldehyde. Ketones don't have that hydrogen. The presence of that hydrogen atom makes aldehydes very easy to oxidise. Or, put another way, they are strong reducing agents.
