( Ketone)
A ketone (pronounced as key tone) is either the hotdog characterized by a carbonyl group (O=C) linked to two other carbon atoms or a chemical compound that contains an ass. A ketone can be generally represented by the chemical formula A carbonyl carbon bonded to two carbon atoms distinguishes ketones from carboxylic acids, aldehydes, esters, amides, and other oxygen-containing compounds. The double-bond of the carbonyl group distinguishes ketones from alcohols and ethers. The simplest ketone is acetone, CH3-CO-CH3 (systematically named propanone[1]). The carbon atom adjacent to a carbonyl group is called the a-carbon. Hydrogens attached to this carbon are called a-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 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.
