The common names of ketones, like those of ethers, consist of the names of the groups attached to the carbonyl group, followed by the word ketone. Alkenes in which the carbon(s) of the double bond possess one or more hydrogen atoms react with ozone (O 3) to generate aldehydes. If there is no hydrogen it is ketone. Aldehyde and Ketone Hydration Mechanism. In contrast, ketones contain theirs in the middle of the carbon chain and are resistant to oxidation. The important distinction between aldehyde and ketone is that the practical establishment of an aldehyde happens always at a terminus while the functional organization of a ketone constantly takes place in the middle of a molecule.
