Aldehyde Introduction: is either a functional group consisting of a terminal carbonyl group, or a compound containing a terminal carbonyl group. Aldehydes are formed by partial oxidation of primary alcohols and form carboxylic acids when they are further oxidized. Low molecular weight aldehydes, e.g., formaldehyde, have sharp, unpleasant odors; higher molecular weight aldehydes, e.g., furfural, have pleasant, often flowery, odors and are found in the essential oils of certain plants. Aldehydes are used for the manufacture of synthetic resins, e.g., bakelite, and for making dyestuffs, flavorings, perfumes, and other chemicals. Some are used as preservatives and disinfectants.

Ketone Introduction: is either the functional group characterized by a carbonyl group linked to two other carbon atoms or a compound that contains this functional group. The simplest ketone, where R and R′ are methyl groups, is acetone; this is one of the most important ketones used in industry. Low-molecular-weight ketones are used chiefly as solvents. Ketones may be prepared by several methods, including the oxidation of secondary alcohols and the destructive distillation of certain salts of organic acids. Ketones are highly reactive, although less so than aldehydes, to which they are closely related.

Hundreds of individual aldehydes and ketones are used by chemists daily to synthesize other compounds, but they are less important in industrial synthesis (that is, the production of compounds on a scale of tons). Only two aldehydes or ketones are used to a significant degree in industry.
