In organic chemistry, a ketone / ˈ k iː t oʊ n / is an organic compound with the structure R−C(=O)−R', where R and R' can be a variety of carbon-containing substituents. Ketones contain a carbonyl group −C(=O)− (a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' is methyl), with the formula (CH 3) 2 CO ...

For example, NaC 6 H 5 CO 2, the sodium salt of benzoic acid (C 6 H 5 COOH), is called sodium benzoate. Where an acid has both a systematic and a common name (like CH 3 COOH, for example, which is known as both acetic acid and as ethanoic acid), its salts can be named from either parent name.
For example, there are at least two isomers of the linear form of pentanone, a ketone that contains a chain of exactly five carbon atoms. There is an oxygen atom bonded to one of the middle three carbons (if it were bonded to an end carbon, the molecule would be an aldehyde , not a ketone), but it is not clear where it is located.
In ortho-substitution, two substituents occupy positions next to each other, which may be numbered 1 and 2.In the diagram, these positions are marked R and ortho.; In meta-substitution, the substituents occupy positions 1 and 3 (corresponding to R and meta in the diagram).
In organic chemistry, the Schmidt reaction is an organic reaction in which an azide reacts with a carbonyl derivative, usually an aldehyde, ketone, or carboxylic acid, under acidic conditions to give an amine or amide, with expulsion of nitrogen.
Chemical nomenclature however (with IUPAC nomenclature as the best example) is necessarily more restrictive: Its purpose is to standardize communication and practice so that, when a chemical term is used it has a fixed meaning relating to chemical structure, thereby giving insights into chemical properties and derived molecular functions. These ...
The position alpha to the carbonyl group (C=O) in a ketone is easily halogenated. This is due to its ability to form an enolate (C=C−O −) in basic solution, or an enol (C=C−OH) in acidic solution. An example of alpha halogenation is the mono-bromination of acetone ((CH 3) 2 C=O), carried out under either acidic or basic conditions, to ...
