Ketone In chemistry, a ketone (alkanone) /ˈkiːtoʊn/ is an organic compound with the structure RC(=O)R', where R and R' can be a variety of carbon-containing substituents. Ketones and aldehydes are simple compounds that contain a carbonyl group (a carbon-oxygen double bond).etones differ from aldehydes in that the carbonyl group (CO) is bonded to two carbons within a carbon skeleton. In aldehydes, the carbonyl is bonded to one carbon and one hydrogen and are located at the ends of carbon chains.

- Ketones and Aldehydes. The carbonyl group is of central importance in organic chemistry because of its ubiquity. Without studying the carbonyl group in depth we have already encountered numerous examples of this functional. group (ketones, aldehydes, carboxylic acids, acid chlorides, etc). The simplest carbonyl compounds are aldehydes and ketones. A ketone has two alkyl (or aryl) groups bonded to the carbonyl carbon.

Chemistry of Enolates and Enols â Acidity of Alpha-Hydrogens In the presence of a base alpha-hydrogens to carbonyl functional group can be abstracted very easily to yield a carbanion. The acidity of the α-hydrogen of carbonyl compounds depends on the stability of the carbanion formed (which is the conjugate base in this case).] α-Hydrogens of Ketones vs Aldehydes. The alpha-hydrogens of ketones (pKa = 20) are less acidic as compared to aldehydes (pKa = 17). This is because the alkyl group R” of ketones pushes electrons via inductive effect on to the alpha-carbon.

Aldehydes and Ketones Nomenclature of Aldehydes and Ketones. Aldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents.If at least one of these substituents is hydrogen, the compound is an aldehyde.omenclature of Aldehydes and Ketones.

Naming Ketones This position of the-carbonyl group (oxygen atom) attached to a carbon atom that is. the last carbon atom in a carbon-chain is important because it distinguishes ketones from a similar category of organic compounds, called aldehydes. (In contrast to ketones, aldehydes include a-carbonyl group attached to the end-carbon in a carbon-chain. ).

What is the most important structural characteristic of aldehydes or ketones? Ernest Z. The most important structural characteristic of aldehydes or ketones is the carbonyl group. Aldehydes and ketones are carbonyl compounds. Ketones have carbon atoms attached on either side of the carbonyl carbon. Aldehydes have either two hydrogen atoms (H₂C=O) or one carbon and one hydrogen (RCH=O)directly attached to the carbonyl carbon. Most reactions of aldehydes and ketones are the same, because they involve the carbonyl group.

14.9 Aldehydes and Ketones: Structure and Names 1 There are five carbon atoms in the LCC. 2  The methyl group (CH 3) is a substituent on the second carbon atom of the chain; the aldehyde carbon atom is always C1. 3  The name is derived from pentane. 4  Dropping the-e and adding the ending-al gives pentanal.

- Where aldehydes and ketones differ An aldehyde differs from a ketone by having a hydrogen atom attached to the carbonyl group. This makes the aldehydes very easy to oxidise.

Pseudohalogen  [show article only]hover over links in text for more info Aldehydes and ketones react with a source of the hydride (H -) ion because the H-ion is a Lewis base, or nucleophile, that attacks the d + end of the C=O bond. When this happens, the two valence electrons on the H-ion form a covalent bond to the carbon atom.Since carbon is tetravalent, one pair of electrons in the C=O bond is displaced onto the oxygen to form an intermediate with a negative charge on the oxygen atom.hen this happens, the two valence electrons on the H-ion form a covalent bond to the carbon atom.

Getting to Know Ketones Ketones are end-products of fat metabolism in the body. That is, they are formed when fat is burned for energy by the muscles. Chemically, they are acids known as ketone bodies, and there are three types: beta-hydroxybutyric acid, aceto-acetic acid, and acetone.

aldehyde aldehyde. an organic compound containing the aldehyde functional group (−CHO); that is, one with a carbonyl group (C=O) located at one end of the carbon chain. Aldehydes are formed in meat during the rancidification of fat and in the degradation of alcohols in biological materials.ach aldehyde is characterized by a carbonyl group (─CO─) attached directly to a hydrogen (─CHO) in its formula and can be converted into a corresponding acid by oxidation, as in the conversion of acetaldehyde to acetic acid.

- Physical Properties Aldehydes and ketones are polar because they contain a carbonyl group (oxygen is very electronegative compared to carbon). Aldehydes and ketones can form hydrogen bonds with water, so small aldehydes and ketones are water-soluble.n an aldehyde, the carbonyl group is on the end of the molecule.
