Acetone (2-propanone or dimethyl ketone) is an organic compound with the formula (CH 3) 2 CO. [22] It is the simplest and smallest ketone ( >C=O ). It is a colorless, highly volatile , and flammable liquid with a characteristic pungent odour, very reminiscent of the smell of pear drops .
WLN allowed for indexing the Chemical Structure Index (CSI) at the Institute for Scientific Information (ISI). It was also the tool used to develop the CAOCI (Commercially Available Organic Chemical Intermediates) database, the datafile from which Accelrys' (successor to MDL) ACD file was developed.
Acetylacetone is an organic compound with the chemical formula CH 3 −C(=O)−CH 2 −C(=O)−CH 3. It is classified as a 1,3-diketone. It exists in equilibrium with a tautomer CH 3 −C(=O)−CH=C(−OH)−CH 3. The mixture is a colorless liquid.

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 ...
Acetophenone is formed as a byproduct of the cumene process, the industrial route for the synthesis of phenol and acetone.In the Hock rearrangement of isopropylbenzene hydroperoxide, migration of a methyl group rather than the phenyl group gives acetophenone and methanol as a result of an alternate rearrangement of the intermediate:

In organic chemistry, an acetyl group is a functional group denoted by the chemical formula −COCH 3 and the structure −C(=O)−CH 3. It is sometimes represented by the symbol Ac [5] [6] (not to be confused with the element actinium). In IUPAC nomenclature, an acetyl group is called an ethanoyl group.
