Aldehyde

An aldehyde is a type of organic compound characterized by a carbon atom double-bonded to an oxygen atom and single-bonded to a hydrogen atom, with the remaining bonds attached to other carbon-containing groups. It is commonly found in natural and synthetic substances, such as in formaldehyde used for preservation or in fragrances. Aldehydes are reactive due to the carbon-oxygen double bond and often participate in chemical reactions like oxidation and addition. They play important roles in the production of plastics, resins, and pharmaceuticals, and are key intermediates in various chemical processes.
