Half-life equation ketone
In organic chemistry, a ketone /ˈkiːtoʊn/ is a functional group 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)− (which contains a carbon-oxygen double bond C=O). The simplest ketone is acetone (where R and R' is … See more The word ketone is derived from Aketon, an old German word for acetone. According to the rules of IUPAC nomenclature, ketone names are derived by changing the suffix -ane of the parent alkane to … See more An aldehyde differs from a ketone in that it has a hydrogen atom attached to its carbonyl group, making aldehydes easier to oxidize. Ketones … See more Ketones engage in many organic reactions. The most important reactions follow from the susceptibility of the carbonyl carbon toward See more Ketones are produced on massive scales in industry as solvents, polymer precursors, and pharmaceuticals. In terms of scale, the most important ketones are acetone See more The ketone carbon is often described as sp hybridized, a description that includes both their electronic and molecular structure. Ketones are trigonal planar around the ketonic carbon, … See more Many methods exist for the preparation of ketones in industrial scale and academic laboratories. Ketones are also produced in various ways by … See more Ketones are pervasive in nature.
