Aldehydes belong to the class of organic compounds which have a general formula as -CHO. They along with the ketones are known as the carbonyl compounds because the carbon is linked to the oxygen atom with a double bond and the rest two side chains of it are bonded with hydrogen and an alkyl group. All the chemical characteristics of an aldehyde are brought about by its carbonyl center.
The dehydrogenation of the alcohols gives rise to aldehydes and they generally have a pleasant smell. Aldehydes are used as solvents and as intermediates in the process of dye production. Moreover, they are also involved in various physiological processes occurring inside the living systems.
Example of Aldehydes:
Formaldehyde, glyceraldehyde, acetaldehyde, glucose, etc. are examples of aldehydes.
