Nomenclature of Aldehydes and Ketones. Aldehydes 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. The IUPAC system of nomenclature assigns a characteristic suffix to these classes, al to aldehydes and one to ketones. For example, H 2 C=O is methan al, more commonly called formaldehyde.ldehydes and ketones are widespread in nature, often combined with other functional groups. Example are shown in the following diagram. The compounds in the top row are found chiefly in plants or microorganisms; those in the bottom row have animal origins.
