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.
a non-polar solvent; used frequently as a building block in organic chemistry Carbon tetrachloride: toxic, and its dissolving power is low; consequently, it has been largely superseded by deuterated solvents: Carbonyldiimidazole: often used for the coupling of amino acids for peptide synthesis and as a reagent in organic synthesis Ceric ...
Ethyl acetate, a nail polish solvent. [1]A solvent (from the Latin solvō, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution.A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
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 ...

Methyl isobutyl ketone (MIBK, 4-methylpentan-2-one) is an organic compound with the condensed chemical formula (CH 3) 2 CHCH 2 C(O)CH 3. This ketone is a colourless liquid that is used as a solvent for gums, resins, paints, varnishes, lacquers, and nitrocellulose.
The equilibrium constant tends to be high in nonpolar solvents; when K keto→enol is equal or greater than 1, the enol form is favoured. The keto form becomes more favourable in polar, hydrogen-bonding solvents, such as water. [7] The enol form is a vinylogous analogue of a carboxylic acid. [citation needed]
