Ketone group
Ketone group

A ketone (pronounced as key tone) is either the functional group characterized by a carbonyl group (O=C) linked to two other carbon atoms or a chemical compound that contains this functional group. A ketone can be generally represented by the formula: Image File history File links Download high resolution version (884x742, 11 KB) Summary Description: Full displayed structural formula of a general ketone (R1C(=O)R2). ...

A carbonyl carbon bonded to two carbon atoms distinguishes ketones from carboxylic acids, aldehydes, esters, amides, and other oxygen-containing compounds.

The carbon atom adjacent to a carbonyl group is called the α-carbon. Hydrogens attached to this carbon are called α-hydrogens. In the presence of an acid catalyst the ketone is subjected to so-called keto-enol tautomerism. The reaction with a strong base gives the corresponding enolate. A diketone is a compound containing two ketone groups. In organic chemistry, keto-enol tautomerism refers to a chemical equilibrium between a keto form (a ketone or an aldehyde) 1 and an enol 2. ...

Nomenclature

Acetone, the simplest ketone
Acetone, the simplest ketone

In general, ketones are named using IUPAC nomenclature by changing the suffix -e of the parent alkane to -one. For common ketones, some traditional names such as acetone and benzophenone predominate, and these are considered retained IUPAC names [2], although some introductory chemistry texts use names such as propanone.

For other uses, see Acetone (disambiguation). ... Benzophenone, also known as diphenylmethanone, phenyl ketone, diphenyl ketone, or benzoylbenzene. ...


Oxo is the formal IUPAC nomenclature for a ketone functional group. However, other prefixes are also used by various books and journals. For some common chemicals (mainly in biochemistry), keto or oxo is the term used to describe the ketone (also known as alkanone) functional group. Oxo also refers to a single oxygen atom coordinated to a transition metal (a metal oxo). The International Union of Pure and Applied Chemistry (IUPAC) is an international non-governmental organization devoted to the advancement of chemistry. ...

In organic chemistry, functional groups (or moieties) are specific groups of atoms within molecules, that are responsible for the characteristic chemical reactions of those molecules. ...


Physical properties

A carbonyl group is polar. This makes ketones polar compounds. The carbonyl groups interact with water by hydrogen bonding, and ketones are soluble in water. It is a hydrogen-bond acceptor, but not a hydrogen-bond donor, and cannot hydrogen-bond to itself. This makes ketones more volatile than alcohols and carboxylic acids of similar molecular weight. A commonly-used example of a polar compound is water (H2O). ... A polar compound is a substance whose molecules have relatively large dipole moments due to non-uniform charge distributions. ...

Structure of a carboxylic acid The 3D structure of the carboxyl group A space-filling model of the carboxyl group Carboxylic acids are organic acids characterized by the presence of a carboxyl group, which has the formula -C(=O)OH, usually written -COOH or -CO2H. [1] Carboxylic acids are Bronsted... The molecular mass of a substance (less accurately called molecular weight and abbreviated as MW) is the mass of one molecule of that substance, relative to the unified atomic mass unit u (equal to 1/12 the mass of one atom of carbon-12). ...


Acidity

The α-hydrogen of a ketone is far more acidic (pKa ≈ 20) than the hydrogen of a regular alkane (pKa ≈ 50). This is due to resonance stabilization of the enolate ion that is formed through dissociation. The relative acidity of the α-hydrogen is important in the enolization reactions of ketones and other carbonyl compounds. In chemistry and biochemistry, acid dissociation constant, the acidity constant, or the acid-ionization constant () is a specific type of equilibrium constant that indicates the extent of dissociation of hydrogen ions from an acid. ... Enol (or, more officially, but less commonly: alkenol) is an alkene with hydroxyl group on one of the carbon atoms of the double bond. ...


Spectroscopic properties

Spectroscopy is an important means for identifying ketones. Ketones and aldehydes will display a significant peak in infrared spectroscopy, at around 1700 cm−1 (slightly higher or lower, depending on the chemical environment) Animation of the dispersion of light as it travels through a triangular prism. ... Infrared spectroscopy (IR spectroscopy) is the subset of spectroscopy that deals with the infrared region of the electromagnetic spectrum. ... Wavenumber in most physical sciences is a wave property inversely related to wavelength, having SI units of reciprocal meters (m−1). ...


Synthesis

Several methods exist for the preparation of ketones in the laboratory:

H3C-CH(OH)-CH3 → H3C-CO-CH3
Two atoms of hydrogen are removed, leaving a single oxygen atom double-bonded to a carbon atom.
  • Ketones are also prepared by Gem halide hydrolysis.
  • Alkynes can be turned into enols through hydration in the presence of an acid and HgS04, and subsequent enol-keto tautomerization gives a ketone. This always produces a ketone, even with a terminal alkyne, and Sia2BH is needed to get an aldehyde from an alkyne
  • Aromatic ketones can be prepared in the Friedel-Crafts reaction, the related Houben-Hoesch reaction and the Fries rearrangement.
  • In the Kornblum–DeLaMare rearrangement ketones are prepared from peroxides and base
  • In the Ruzicka cyclization, cyclic ketones are prepared from dicarboxylic acids.
  • In the Nef reaction, ketones form by hydrolysis of salts of secondary nitro compounds
  • In the Fukuyama coupling, ketones form from a thioester and a organozinc compound

Biochemistry

Acetone, acetoacetate and beta-hydroxybutyrate are ketones (or ketone bodies) generated from carbohydrates, fatty acids and amino acids in humans and most vertebrates. Ketones are elevated in blood after fasting including a night of sleep, and in both blood and urine in starvation, hypoglycemia due to causes other than hyperinsulinism, various inborn errors of metabolism, and ketoacidosis (usually due to diabetes mellitus). Although ketoacidosis is characteristic of decompensated or untreated type 1 diabetes, ketosis or even ketoacidosis can occur in type 2 diabetes in some circumstances as well. Acetoacetate and beta-hydroxybutyrate are an important fuel for many tissues, especially during fasting and starvation. The brain, in particular, relies heavily on ketone bodies as a substrate for lipid synthesis and for energy during times of reduced food intake. At the NIH, Dr. Richard Veech refers to ketones as "magic" in their ability to increase metabolic efficiency, while decreasing production of free radicals, the damaging byproducts of normal metabolism. His work has shown that ketone bodies may treat neurological diseases such as Alzheimer's and Parkinson's disease,[4] and the heart and brain operate 25% more efficiently using ketones as a source of energy.[5] For other uses, see Acetone (disambiguation). ... Acetoacetic acid (also known as 3-oxobutanoic acid or diacetic acid) is a beta-keto acid of the keto acid group, its empirical formula is C4H6O3 or CH3COCH2COOH.
