Keto groups are found in a variety of organic compounds, including ketones, aldehydes, carboxylic acids, and amides. Ketones are organic compounds that contain a keto group bonded to two other carbon atoms. Aldehydes are organic compounds that contain a keto group bonded to one carbon atom and one hydrogen atom. Carboxylic acids are organic compounds that contain a keto group bonded to a hydroxyl group (-OH). Amides are organic compounds that contain a keto group bonded to a nitrogen atom.
The keto group is a reactive functional group that can undergo a variety of chemical reactions. These reactions include nucleophilic addition, electrophilic addition, and oxidation-reduction reactions. Keto groups can also be dehydrated to form enols, which are compounds that contain a double bond between a carbon atom and an oxygen atom.
Keto groups are found in a wide variety of natural products and synthetic compounds. Some examples of compounds that contain keto groups include acetone, formaldehyde, acetic acid, and urea. Keto groups are also found in many drugs and pharmaceuticals, such as aspirin, ibuprofen, and paracetamol.
