16. 1 structure and bonding: an aldehyde contains a carbonyl group bonded to a hydrogen atom and a carbon atom, a ketone contains a carbonyl group bonded to two carbon atoms. 16. 2 nomenclature: an aldehyde is named by changing the -e of the parent alkane to an -al, a ketone is named by changing the -e of the parent alkane to. 16. 3 physical properties: aldehydes and ketones are polar compounds that engage in dipole-dipole interactions in pure liquid, they have higher boiling points than nonpolar compounds of comparable molecular weight. Ch16: aldehydes and ketones: many of these reactions form new carbon-carbon bonds, making this a very important class of organic synthesis. 16. 9 keto-enol tautomerism: the carbon atom adjacent to the carbonyl group is called an. Oxidation: aldehydes are easily oxidized to carboxylic acids using a variety of reagents, including chromic acid, silver salts, peroxides, and molecular oxygen o2.
