Aldehydes, Ketones, and Carboxylic Acids are carbonyl compounds which contain a carbon-oxygen double bond. These organic compounds are essential in the field of organic chemistry and also have many industrial applications. The presence of the common carbonyl group in the two classes of compounds makes them display similar chemical properties. However, aldehydes are more reactive than ketones because of the presence of free hydrogen atom. Organic compounds containing a carbon-oxygen double bond called the carboxyl group, which is one of the most important functional groups in organic chemistry. Aldehydes and ketones are obtained by ozonolysis of alkenes, by hydration of alkynes and by the oxidation of alcohols or form cyanides. Carboxylic acids are obtained by the oxidation of primary alcohols or aldehydes. Carboxylic acids are more acidic than alcohols or phenols due to resonance stabilization. Studying the chapter “Aldehydes, Ketones and Carboxylic Acids” will help you to write IUPAC names and common names of ketones, aldehydes, and carboxylic acids.
