Cyclische ketone
WebThe open-chain ketones in question have the formula R'-CO-R2, in which R 'and R2 can each independently contain 1 to 15 carbon atoms in the chain, so that R' + R2 have a maximum value of 30 and a minimum of 2 can. The chains can in turn be substituted with alkyl groups of 1 to 6 carbon atoms. Cyclohexanone and cyclohexanone substituted with … 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.
