WebKetones are named following IUPAC nomenclature. They are named by finding the carbonyl group and identifying it with a location number, if necessary, then adding the suffix "-one." The common name for ketones is determined by naming the alkyl groups attached to the carbonyl (in alphabetical order), then adding 'ketone'. WebCyclohexanone Some aliphatic ketones contain a ring structure, which classifies them as cyclic aliphatic ketones. An example of such a compound is cyclohexanone which is a cyclic...

WebAldehydes and ketones are organic compounds which incorporate a carbonyl functional group, C=O. The carbon atom of this group has two remaining bonds that may be occupied by hydrogen or alkyl or aryl substituents. If at least one of these substituents is hydrogen, the compound is an aldehyde. If neither is hydrogen, the compound is a ketone. WebCyclopentanone is a cyclic ketone that consists of cyclopentane bearing a single oxo substituent. It has a role as a Maillard reaction product.
